Travis has lived the life of a foster-care orphan. He has a short temper. He has court-ordered therapy. He has a whole bunch of mystery surrounding a photograph of the man who might be his father - a man with eyes just like his: one red, and one blue.
The story is intriguing - we know that there's something seriously sinister going on, and the layers are peeled back to reveal just a tantalisingly small amount of the truth at a time. It definitely keeps you reading.
Overall, the book has a fab gothic/horror/freaking weird vibe. As that's my kind of thing, I definitely enjoyed it. It's likely to appeal to people who enjoyed The Crow (US link,) V for Vendetta (US link) - y'know, the grittier side of things.
It probably goes without saying, but if you're not a fan of horror, demons, and bloody violence, this is probably not for you.
There's the occasional feeling of disjointedness (you know, the 'who was he again?' 'what's he doing?' kind of feeling,) but it's exceedingly small.
