way!” Jack snorted. Now that she was 11, Ashley had a little more attitude, but, being two years older, Jack could handle it. Turning to their newest temporary foster child, Jack said, “Sammy, you’ve got to ignore all this blood-sucking stuff. You heard the ranger. The only blood-sucking bats live far, far away from here. The ones in Carlsbad are Mexican free-tailed bats. Free-tailed bats eat tons of bugs, so they’re good bats,” Jack declared. “And I was never afraid of any bats.”
“Liar,” Ashley laughed. “So who do you think is telling the truth, Sammy? Me, or my mean brother, who used to terrify me with spooky stories when he was really the one who was scared?”
Ducking his round, blond head, Sam whispered, “I d-d-don’t know.” He began to fidget with the end of his dirty shoelace so that, Jack guessed, he wouldn’t have to look at either one of them. Although he’d been with their family for three weeks, Sam still didn’t know the Landons well enough to understand the way Jack and Ashley teased. Well, from what Ms. Lopez, Sam’s social worker, had told them, there hadn’t been much in the boy’s life to laugh about. That was why Jack’s mother and father were glad Sam could go with them all the way to New Mexico to see the magnificent cavern of Carlsbad. “If anyone deserves a break,” Jack’s father, Steven, had said, “it’s this kid.”
Jack looked up to see a watery moon appear like a ghost in the sky, faint and silvery in the twilight. The clouds seemed to blaze even brighter as the last rays of sun set them on fire. If the bats flew out soon, Jack would have a perfect canvas to frame them. Focusing his lens, he snapped a picture of the clouds, double-checking that his flash was off. The ranger had instructed all of the visitors to turn off their camera flash attachments, since the sound from a flash—even though humans didn’t notice it—might throw off the bats’ sensitive navigation system.
Barely tapping his shoe with the edge of his worn sneaker, Sam looked at Jack with large eyes. His hair was clipped ragged, as if he’d trimmed it himself. But what kind of eight-year-old would cut his own hair? Not anyone who lived in the Landons’ Jackson Hole neighborhood, where all the kids had their own bikes and computers and enough money in their pockets to buy fast food whenever they wanted. Although Sam hadn’t told them much about his life, Jack could tell he came from a different world, a world Jack was glad he didn’t live in.
“So J-Jack, you’re not really s-c-c-ared? Of the b-b-bats?”
“Nah. Ashley and me, we’re just kidding around. Don’t take us seriously.”
“OK. I’m not s-s-scared, either.”
Mmmm, maybe not of the bats, Jack thought. But ever since they’d had him, Sam had seemed, if not frightened, at least nervous all the time. Did some unknown fear make Sam stutter the way he did? The poor kid couldn’t get out two words without stuttering. Sometimes he’d start to say something and then just give up, as though whatever he’d wanted to say simply wasn’t worth the struggle to force it out. Ms. Lopez had said that although Sam’s school grades were poor because of his stuttering problem, inside he was really a bright little boy.
Just then Ashley grabbed Jack’s arm and pointed excitedly at a small black object streaking by. “Is that one? Quick—take a picture! It’s right there—see?”
“Duh. That’s a cave swallow,” Jack replied. “It has a beak. Bird—beak. Bat—ugly gargoyle face. Get the difference?”
“If you call them ugly, they’ll hear you and stay there in the cave all night and they’ll never come out,” she declared.
“Honest?” Sam worried.
Jack assured him, “No, Sammy, Ashley was only joking again.”
“But we’ve been waiting an awful long time,” Ashley said, sighing. “Mom, do you think they’re ever going to come out of the cave?”
“Hmm?” their mother, Olivia, murmured, barely looking up from a stack of papers. A yellow highlighter was poised in her hand, and every few minutes she underlined a sentence or bracketed a paragraph until the paper seemed to glow neon. A wildlife veterinarian, Olivia Landon had come to New Mexico to study the decline in the number of bats occupying Carlsbad Cavern. Mountains of scientific papers had been faxed to her before they’d left their home in Wyoming, which meant that for the entire trip on the plane, she’d been nose-deep in study. Jack had never seen her read so much so furiously.
“Earth to Mom,” Ashley cried, cupping her hands around her mouth. “You’re the expert. Do bats ever stay inside the cavern and just skip a night? Because I think that might be what they’re doing here.”
Looking up, Olivia blinked. “Skip? Oh, no. Don’t worry, sweetheart, they’ll fly. You just have to be patient. Remember, bats are wild animals, not a circus act trained to appear on cue.” Taking off her reading glasses, Olivia rubbed the bridge of her nose. “What makes them swarm is one of the great bat mysteries. Even the latest research—” she tapped her glasses onto the paper—“even this can’t explain why they fly out the way they do or why they choose the particular moment they decide to emerge.”
Olivia’s dark, curly hair had been pushed up under a baseball cap, although strands escaped in tendrils that wound past her shoulders. Her hiking boots, scarred from years of climbing over rough terrain, were the same tan as her legs. Ashley was a smaller version of Olivia, with the identical olive skin that just grew darker throughout the summer. It was Jack and his father who had to slather on sunscreen or risk burning to a crisp. Jack, Steven, and now Sam, who shared their fair coloring.
“By the way,” Olivia said, “can any of you kids see where your dad’s gone off to?”
Scanning the crowd, Jack looked for a tall, blond head, but it was useless. So many people had crowded together on the benches that it seemed as though a giant handful of confetti had been tossed into the amphitheater. He was about to say that there was no way anyone could spot
anyone in that place when Sammy announced, “He’s over th-there, with that r-ranger.”
“Way to go, Sammy! Could you go get him for me?” Olivia asked. “He’s not too far from here. I’ll watch you the whole time.”
Sam shook his head no.
“OK, how about if Ashley goes with you. Would that be all right?”
Without answering, Sam nodded. Following Ashley, he made his way toward the ramp, his sturdy legs pumping hard to stay right behind Ashley as he climbed the stone steps.
“At least Sam went with Ashley,” Olivia said to Jack. “He’s becoming far too dependent on you, Jack.”
“Hey, Sam’s OK,” Jack countered. “He’s doing better.”
“Better with you,” Olivia reminded him. “Not better with your dad or Ashley or me. You’re the only one out of all of us he feels really safe with.”
That much was true, and all of the Landons knew it. When Ms. Lopez had arrived with Sam, he’d clung to her, big-eyed and silent.
“Sam, remember what we talked about,” Ms. Lopez had said in her gentlest voice. “Since your mother is so sick, the Landons are going to take care of you, just until your own mom gets better.”
“Hi, Sam,” Olivia had said. Bending down to eye level, she’d reached out her hand, but Sam had shrunk back behind Ms. Lopez’s green dress
