Hi! My name is Janie Ray, and I'm 11 years old. When I first got this diary from my mom, I didn't think I'd have all that much to write about. I mean, let's face it - fifth grade isn't exactly the most exciting thing in the world. But then, really strange things started happening. Like last week, my best friend Sheila and I were hanging out in our clubhouse, drinking lemonade and trying to figure out what to do about Marcia the Snob, when we suddenly noticed a weird inscription on this old medallion I found when I was little.

Twelve-year-old cousins Sophie and Jessica don’t have much in common. Sophie loves hiking and her small town. Jessica would rather be shopping in a city. The only mystery is how they’ll be able to spend the summer together. Then they find a briefcase in the forest with a surprise inside. When they hear footsteps behind them and bad guys run after them, they have no choice but to work together to solve the mystery of the feather chase.

Jen did not want to leave the city. She did not want to move to a farm with her mom and her mom's new boyfriend, Walter. She did not want to leave her friends and her dad. Most of all, Jen did not want to get new "sisters", Andy and Reese. As if learning new chores on Peapod Farm wasn't hard enough, having to deal with perfect-at-everything Andy might be the last straw for Jen. Besides cleaning the chicken coop, trying to keep up with the customers at the local farmers' market, and missing her old life, Jen has to deal with her own insecurities about this new family.

Becca Singer is having the Worst Day Ever. Her best friend, Harper, dumped her, and Becca is totally friendless and alone. Then the box arrives in the mail. Inside the box? One bracelet, plus a mysterious note telling Becca to make a wish. So Becca puts on the bracelet—why not, right?—and wishes to have friends. Lots of friends. So many friends. And just like that, the magic works. Suddenly, EVERYONE wants to be Becca's BFF, from all the kids at school to the teachers (!) to her own mom (!!).

Almost a year has passed since Stella and Tom discovered a time tunnel and travelled to early 1900s London, where they befriended Emma, Lucy ,and Jack. The magical moles that made the tunnel and secret lake appear have since vanished, but the children are longing to meet again. Then an illness, which puts Emma’s life in danger, changes everything. The moles reappear, just when needed, and Lucy realizes the only hope of finding a cure lies in the future.
