The last in the Soldier Son series. The reviewers on Amazon seem not to have enjoyed this one very much, but I thought it was pretty decent; my only regret was that it really is the end of the series, and it's unlikely to get resurrected in the way the Fitz books were. Anyway, if you've read the previous two books in the series you'll want this one regardless of what I say here, and if you haven't read the previous two books then this won't make any sense at all.
I still don't understand why the newer paperback edition of "Forest Mage" has a fish on it, though.
