Passage continues a wonderful series but ultimately its story is fairly singular in purpose. If the author had added something more I think this book would have really stood out amongst the others in the series.
Penric's Mission lifts the main character to new heights in terms of his confidence and maturity. This it the Penric I've been waiting for and the one which makes this fourth book in the series a must read.
Sly Mongoose by Tobias Buckell is a fast-paced science fiction novel that centers around Pepper, an elite soldier whose primary duty is the preservation of the human race (kicking ass is his other priority). A fun read that I highly recommend.
This next installment in the Penric and Desdemona series goes a little deeper than previous stories, but not deep enough to rise above a three rocket rating. Still, it's a good read and a nice addition to the ongoing saga.
