Hey there. I really like the novels, but not all of them are the same level of quality. See Enderverse for a list of all the novels and sub-series. I highly reccomend Ender's Game, the original novel, as well as the rest of the Ender Quintet. The rest of the Ender Quintet is very different from Ender's Game, however, they are very philisophical and wordy, aside from Ender in Exile. The Shadow Saga is another sub-series, and is more similar to the child soldier kind of stuff from Ender's Game. The First and Second Formic Wars are very action-oriented and sci-fi. So, you can really choose which series sounds the best to read, but the only one I can reccomend to everyone is Ender's Game.
