Book Description: Unless, Vel, an immortal time-jumper, can help out his younger self, his tribe's descendants--a big chunk of the 21st century British population--will be eliminated from the timeline. Present-day Vel, though, has problems of his own, so he takes a chance and outs himself (and his talented teen-aged daughter Quince) to Joe Tavistock, a techie turned "half-cop" contracted to the British Home Office, making it Joe's problem. Joe's superiors are dubious, and Joe doesn't know who to trust. The stakes are high not just for Vel, but for everyone involved.
