Just finished Hawk Channel Chase by Tom Corcoran - but not on my iPad (he does not do e-books... never has), so I suppose that does not count.
On the iPad, I last read "With the Old Breed" by Eugene Sledge, a first-person account of the War in the Pacific. If you like History at all, highly recommended.
Next in line is either "61 hours" by Lee Child or Randy Wayne White's latest, "Deep Shadow". Whichever of those two - light summer reading escapes - that I choose, after that is finished I plan to read "The Road" by Cormac McCarthy.
Haven't planned out my summer reading any further than that yet...
