On paper: Assassin's Creed - 'Forsaken'. This is a ripper of a series, haven't played the games though.
On tablet: Clive Cussler - 'Trojan Oddyssey'.
I'll probably die of a surfeit of Cussler, as I was recently given most of his books in e-book format.
Oh, and I've been re-visiting the great Edgar Wallace, and 'Sapper' (author of the original 'Bulldog Drummond' books).
