Thurman, Rob -- Blackout [e-book purchase]

When the author pulls amnesia in the sixth book of a series, it's a strong sign that she is out of material. This isn't purely a book of "erase the protagonist's memory so we can retread everything cool from the previous books"; there's some attempt to work in character growth, as Monster Boy and His Brother react to the situation. But -- not enough to justify a sixth book. I'm sorry; the fun has not run out of this series, but this is not the way to stretch the fun.
