I'm so glad you liked Winter Tide! If you're up for it, an Amazon review saying so would get me closer to their threshold for promotions, and thus help increase the odds of future books past Deep Roots. (I hate to point people at them specifically, but their ratings get used for everything and it really does help.)

Re paperback edits: You can't make major changes, but they'll usually let you fix typo-level stuff. Happily there are few such corrections for Deep Roots, because I had a great editor and copyeditor.
