I can imagine it would be exceptionally hard to keep up the rational, plausible explanations for Rin's "magic" through a second book, and the author doesn't really try in this one, not by the end.

First off, Ozzy is running into the ocean in trances. He's asleep or unconscious when he does it, and almost drowns. It becomes a thing Sigi and Clark are worried about, throughout. It has a purpose, although the explanation / significance isn't explained until the end. It has to do with becoming an "apprentice."

Secondly, Rin doesn't play as big a part in this book, although he's a presence. His magic is not up for question, not like it was last time.

In this one, Ozzy matches wits with the mastermind behind his parents' kidnapping and disappearance. He makes a bunch of mistakes, not the least of which is assuming Rin's magic is behind a a plane ticket to New York and a thumb drive that show up on his doorstep. He just doesn't think things through, he's so eager for the "magic" explanation to be the true one and for Rin to appear and rescue him -- again.

In addition, secret-weapon Clark is a secret no longer. In fact, he's a prized trophy, if the new bad guy can catch and hold onto him (easier planned than done).

Ozzy learns what his parents discovered, and that he has the key to it, and he's pursued by hired mercenary Jon after they escape the villain in New York.

Jon kinda loses it -- professionally and emotionally -- and his ability (or not) to capture Sigi, Clark and Ozzy gets personal, real fast.

Sheriff Wills is on the teens' side this time, trying to keep them safe from Jon, not that he's terrifically effective.

I won't spoil the ending. Read and enjoy!
