Like the other library print book I looked at recently, I can't really review this one because I made it through only the first four chapters before giving up. They story switched back and forth (or even froth as I originally typed it! LOL!) between the two main characters and it wasn't making a whole lot of sense, much less as it drawing me in. One character, the guy, was named Fin, which turned me right off. 'Fin' is almost as bad as 'Jack' for an adventuring character name and the lack of originality in choosing either of those names frankly nauseates me. I flatly refuse to read any novel where the main character is called Jack on principle, no matter how tempting it sounds. The girl is named Marrill, which is almost equally obnoxious.
This is supposedly a middle-grade book, but the page count is well over four hundred - much too long for a middle-grade book unless the book is exceptional and really has something to offer, and this one didn't feel that way to me. It's also odd that it's so long, because it's not a one book story! It's part of a series, and I sure don't do series unless they're exceptional, so this one loses on that score, too. This authors need to seriously redact their work! OTOH, maybe this is what happens when you try to co-author a novel: it bloats!
As if that's not bad enough, Fin is an orphan who is in search of his mom, and there's a bumbling wizard. Yuk! It sounds vaguely reminiscent of the Terry Gilliam Movie Time Bandits, but it's not Gilliam and it shows. So, based on what little I looked at, I can't recommend it. But also based on what little I looked at, this review may be useless to you and if so I apologize, but I could not get into this book at all, and life is too short to spend pursing things that don't instantly delight you as a reader!
