This is more of a lighter sci-fi adventure/fantasy type book, light on the hard sci-fi. I really, really enjoyed this. I loved the characters. They were complex and interesting without feeling over the top. The plot wasn't anything super new, but it was done well, in an interesting way. I particularly liked the travel through grimspace and Jax's descriptions of what it felt like. I had a minor quibble with the ending (view spoiler)[in that it felt an awful lot like the ending to Serenity. And did the author really have to kill off baby-Z? There may have been a tear or two shed for him (hide spoiler)]. Anyway, this was definitely a fun, fast paced book and I can't wait to see what the rest of the series has in store for me.
