Ooooh we have similar tastes cause I loved all of those. Igantious was a selfish moron, but an endearing selfish moron I was rooting for by the end.

Dark forest was my personal favorite of the Remembrance trilogy, it has deeply colored my view of any potential IRL aliens in the universe.

A word of warning though, after the trilogy a fan fiction by a different author picked up steam as the "unofficial 4th book" and was even packaged with the original three by the publishers. However, The Redemption of Time is pure stinkin' hot doggie doo-doo. Stay away and let the story end where the Liu Cixin intended.
