I've been looking for a Sci-fi book trilogy that I'm pretty sure was published 2000-2004. Almost positive I read it in high school, think it might fall under YA or something but anyway details that I remember:
The first book starts out with us getting details about the protagonist via dreams I believe. Something about his ship being damaged or lost during the transit home after the war and the soldiers are debriefed during hypersleep. Well, because his ship was damaged/lost, the system never stops the debriefing and forces him to relive the experiences over and over again which causes a lot of trauma to the point where he has constantly recurring nightmares involving those memories.
Anyway, you find out he was a soldier who fought with a power suit of some kind and his branch of the military didn't believe in harming the environment. They fought what he called a "Pure War", only causing destruction to the enemy never the surrounding life. The last war he fought was against some kind of bugs.
Apparently his unit was sabotaged by the local populace who were supposedly helping them with upkeep. The mechanics were putting some kind of alien eggs inside the suits so that they would cause the wearer to go battle crazy and then the suits would explode from the inside out as the alien bug ripped out from their bodies.
He later meets some kind of orphan/thief/beggar girl who you believe is super young at the time. She helps him out because at some point, I don't remember why or how, he has to go on the run from the government.
That's a lot from the beginning of the first book. I don't really remember how it ends but the girl ends up having special abilities later in the series, and you find out that there is an alien inside the protagonist's suit but it's not the bug alien but a different kind/species. Last but not least, the girl and protagonist end up as lovers at some point during end of the first or middle of the second book. I'm not too sure.
Anyways, I hope someone can help me out with this, it's been driving me bonkers. I remember some other stuff, like specific scenes if you think those would help.
