I use a Kindle Touch and a Kindle Fire.I've read all five, loved them all to varying degrees, and I can't wait for the sixth book. That being said... I think the fifth and most recent book was by far the worst. So bloated and sloppy it reminded me of a WoT novel. Book 4 gets all the hate but, for me, it's miles better than numero 5. Hoping GRRM rebounds as this next one is the penultimate in the series.
