SONGS OF LOVE AND DEATH on Kindle
The link for the Kindle edition is here. Current price says $12.99. (Please note, this information is subject to change. There were issues with the availability of the Kindle version of WARRIORS when it came out in March, and I hope that won't happen again.)
I have no idea about the availability or pricing for other e-book versions. And no, I don't actually own a Kindle. <g> Just passing this information along, for what it's worth.
