The Blood of a Time Lord

Fleeing from an unknown enemy, Peter Quill and the rest of the Guardians run into a strange and witty man who calls himself the Doctor. Little do they know, he's the only one who can help them get back home, protect Xandar, and save Peter from horrendous fate.

[Story is set when Rose and the 10th Doctor are still traveling together and about a year after the Guardians defeated Ronan]
