When summer comes around, it's off to the beach for Rosalind...and off to Maine with Aunt Claire for the rest of the Penderwick girls, as well as their old friend, Jeffrey. That leaves Skye as OAP (oldest available Penderwick)—a terrifying notion for all, but for Skye especially. Things look good as they settle into their cozy cottage, with a rocky shore, enthusiastic seagulls, a just-right corner store, and a charming next-door neighbor. But can Skye hold it together long enough to figure out Rosalind's directions about not letting Batty explode?

Claudia's sister, Janine, is too busy being smart to be nice to anyone - even their grandmother, Mimi. But Claudia doesn't have to see Janine too much this summer, since the Baby-Sitters Club is starting a new play group. It's going to be so much fun! But then Mimi has a stroke, and the whole summer changes. Now Claudia is "Mimi-sitting," and Janine is no help at all. How can the Kishi sisters get along when Janine is always so mean?

There lived a girl named Petra Peña, who wanted nothing more than to be a storyteller, like her abuelita. But Petra's world is ending. Earth has been destroyed by a comet, and only a few hundred scientists and their children - among them Petra and her family - have been chosen to journey to a new planet. They are the ones who must carry on the human race. Hundreds of years later, Petra wakes to this new planet - and the discovery that she is the only person who remembers Earth. A sinister Collective has taken over the ship during its journey.
