Cryoburn (Lois McMaster Bujold)

Any Miles Vorkosigan story is a wild fun ride. This one starts with Miles, in a hallucinatory reaction to bad drugs, stumbling through a dark maze in an abandoned cryosleep storage facility, and ends with him on the way home having wrested triumph from the grip of evil money-hungry corporate executives. Along the way various people on both sides of the struggle are kidnapped, there's a brief mixup in the shuffling of frozen folks, and some lessons in the art of soliciting bribes as an investigative technique. As Miles ages, with wife and children to think of, there is less of the frenetic action of previous stories, but still a satisfactory sense that the poor lords of commerce with their long-term plans of financial conquest have no idea what they're up against until it is far, far too late.
