This book has been on my to-read list for some time, not least because I was impressed by the way the author debuted this book during an extremely trying personal time (his daughter was sick with a tumor and he made it clear his priority was with his family).

But dealing with mean girls isn't the worst of Abby's problems. An unscrupulous scientist has kidnapped her grandfather and her parents, and unless Abby and Derick can solve a series of clues to uncover their grandfather's secrets, their parents might meet an untimely death.
I thought this was a cute story--there's a lot to love in the setting and all the fun technical tools Abby and Derick use, and the various clues were interesting and inventive. This isn't the kind of middle grade you read for the style (as you would Gary Schmidt or ClareVanderpol), but for plot. Though there were a few elements that stretched my credulity (Abby's friend Carol seemed a bit over the top, and the whole thing about the clues seemed more like an interesting plot device than a realistic ploy), the book was fast-paced but still had heart. I think my 8 y.o. son would enjoy this a great deal.
