Lucy and her pack are back, in this sequel to Beth Vrabel’s heartwarming and humorous debut, Pack of Dorks. Sheldon convinces Lucy, Sam, April, and Amanda to join him at a weeklong sleep-away summer camp—Camp Paleo: Live Like a Caveman. Like cavemen, they’re going to have to make do without air conditioning or a heated pool. They’ll learn archery and dig for fossils. And Grandma’s coming too; she’s taking a job as lunch lady for the camp next door.

At the last minute, Sam backs out to go to a gymnastics training camp instead. Lucy wonders why she misses him so much—it’s not like he’s her boyfriend or anything. Why does the word “boyfriend” make her blush, even when she’s only thinking it? She needs a distraction. Enter Mr. Bosserman, the grouchy camp leader who won’t budge on the caveman aspect of the camp. The old man needs some softening up, and Lucy knows just the person for the job: Grandma.

One successful match made, Lucy starts to see potential lovebirds everywhere. And setting up couples keeps her from facing the question tickling the back of her mind: Is she in love with Sam? But when the wrong campers fall for each other, the pack falls apart, all under the watchful eye of a super secret blogger who’s been writing about the camp’s activities Gossip Girl–style. Even worse? A thief is targeting everyone but Lucy, setting her up to look guilty. Soon Lucy again finds herself alone, left to fix the messes she’s made and face her own feelings. If she fails, the pack may be splintered for good.
