Okay, so I have to state my main case for this book right away, because it's remarkable.
This author works with a complicated, multi-level, thrillerlike plot like a BOSS.
I was hooked within the first ten pages. The plot is interesting, dynamic--small conflict, and not-so-small, in every scene--and it's handled so well, so suspensefully, that I knew I could trust every small out-of-place plot hair to have its own particular meaning by the end of the novel. This is rarer than it should be, and thus, even on its own, deserves five stars.
And the action is pretty nonstop, as well. Even the quiet scenes--one of my favorites features the homeless main character, young River, in an IHOP--have an element of suspense (River is, at that point, wanted by the police) that go a long way towards driving the plot forward all day, E'REY DAY, just as a plot should be driven forward. Conflict in every scene, again, without it feeling obvious or forced. Hats off. Hands together.
The main character is extremely likeable, too. River's schizophrenia confuses me a little--it seems to mainly manifest itself in lightbulbs singing thematically appropriate songs out of key, and it isn't made clear, by the end of the novel, how much of his 'disease' is actually a disease, and how much of it is River's unusual gift--but River himself is a sweet kid, and you want him to succeed and find a better place for himself. Secondary characters--including especially Sammie, a familially influenced 'government' agent, her old-soldier father, and two very mafia-style crime bosses--are given clear motivation for doing the things they do, and the more prominent among them (again, Sammie especially) have well-developed character arcs. A good job was done, in fact, adding characterization to a plot based story. This can be difficult to do, and it's honestly somewhat impressive. Again, hats off.
Even setting is handled well. The main city (Centerville? River seems to have some trouble remembering the name) is described well through the eyes of a young homeless man. A little TOO well, I thought at several points, as River himself is just passing through, and hasn't lived there his whole life. The extra-dimensional scenes (again, not going to spoil anything for you, but there are some) offer a little less physical detail, and I'm still on the fence about whether I agreed with that writing path or not. I was curious about the extra dimensions, and I didn't feel like my curiosity was properly assuaged.
On the other hand, it's the first book in a series, so, you know. I guess I'll buy the next one and see for myself. :)
Highly recommend it, especially for fans of paranormal fantasy, urban fantasy, secret agent style thrillers, and YA literature (for this book has, at its core, a coming-of-age flavor that fits in well with YA). The writing is clear and carefully managed, and you'll find yourself following the complicated plot with ease--and having a lot of fun along the way.
