Welcome to the site. As far as reading goes I would for you, recommend starting with Imagination, because you were just told to. Read Necromancer before Death's Song. It's a good start on EndMasters tamer stories
A Stack of Cats is good if you want to play a puzzle game.
Marooned on Giri Minor is solid if you want to play something sci-fi. It's also got a sequel if you like it.
