Consider Phlebas by Iain M. Banks (Scottish, 1987)

Summary:
Horza Bora Gobochul is a Changer, a human species modified to be able to morph into other people and is working for the Idirans during the Idiran-Culture war. While on an undercover mission on the planet Sorpen, he is made by the on-site Culture agent Perosteck Balveda and is sentenced to death by choking on human waste. However, he is timely saved by an Idiran mission directed by Horza’s friend, the Querl Xoralundra. The Querl tells Horza they are there to capture Balveda and that they saved him because they want him to do a mission. It seems like a state-of-the-art Culture Mind, a super intelligent computer that control space vessels, escaped the destruction of the ship it commanded and is now stranded on a neutral planet under control of the Dra’Azon, a race of poweful non-corporeal beings. As Horza used to live there and the Dra’Azon limits entry to most beings except to Changers, he is the best choice for the extraction. Horza accepts the mission on the condition that he be released from duty once the extraction is done. With that half-promised by Xoralundra and after visiting a now prisoner Balveda, he embarks on his last mission to one of the so-called Planet of the Dead: Schar’s World.

Another summary:
It all starts with Horza about to die in space. He got captured by some guards. Amahain-Frolk, the security minister and The Culture agent Balveda arrived. Balveda asked him not to kill Horza. The Idirans, a religious society, and The Culture, a very advanced civilization, were at war and Horza was a spy. There was a battle in space. A light cruiser rescued Horza. The Idirands captured Balveda and wanted to execute her. The Idirans needed Horza to get to Schar’s World, a planet where the Idirans and the Culture could not enter. On his way, Horza got captured by another ship named the Clear Air Turbulence and then by a tribe from which he escaped by poisoning the leader. Horza was a Changer so he could take the appearance of other people. He took the shape of captain Kraiklyn and kills him. He met Balveda and she told the crew who he really was, but he convinced them to join him on his mission to get Schar’s World. They got to Schar’s World and started looking for the Mind. The Idirans had control of the Mind and they didn't kill Balveda because they didn’t know about the alliance. They got into a battle with two Idirans and Xoxarle, one of them, killed Horza. Balveda killed Xoxarale. The Mind was back under the control of the Culture. The Idirans died in several ways, some were sent to Homomda and some of them even joined the Culture.
