I admit I wasn't expecting much when I picked up this series, but am I ever glad that I gave it a try! For the first couple chapters, I had a little trouble getting into the author's style, and usually when that happens, it makes an impression that I can't get away from. This series absolutely decimated it--so much so that by the end of the first book, I didn't even remember that I'd ever had trouble--until the pattern repeated itself in the next book. (For the record, there's nothing wrong with the style; it just takes me a little while to get into the stride.) All that to say I've never had a book overcome an initial impression like that, so the fact that these did is an amazing testament to the power of the story and the characters.
Wow--the characters! I keep thinking that Brock Eastman must have been spying on my house growing up; that's how real the sibling relationships feel. Setting aside the fact that we were never on a life-or-death race through outer space to save our parents from their evil captors, I can't shake the feeling that parts of the dialogue, the relationship dynamics, and the character traits really are my siblings and me. The plot keeps me on the edge of my seat every moment without overwhelming me like some other books I've read. There's also plenty of humor sprinkled throughout.
One of my favorite aspects of this series is the way that it sticks to straight sci-fi without adding in fantasy elements. Even the strangest parts of this outer-space world (blue people???) are given a scientific or technological explanation (even if an imaginary one). I'm not a huge fan of most fantasy, and it's hard to find good science fiction that doesn't let some of those elements creep in. Not that this series wouldn't appeal to fans of fantasy as well--there's plenty of epic struggle, bizarre creatures, and evil overlords to go around! The story is also explicitly and unashamedly Christian, although it takes the characters a little while to realize the full meaning of the truth they're seeking.
I accidentally started with the second book in the series and was still able to follow the storyline, but I definitely recommend reading them in order. The series so far is 1) Taken, 2) Risk, 3) Unleash, 4) Tangle
(with a few additional short-story spin-offs). I'm holding my breath for the release of the conclusion--Hope!
