Time for Yesterday by A.C. Crispin

4.0

A strong sequel to [b:Yesterday's Son|216700|Yesterday's Son (Star Trek, No 11)|A.C. Crispin|http://photo.goodreads.com/books/1172784973s/216700.jpg|1591026], continuing the story of Zar in the distant past of Sarpeidion. Crispin creates an entertaining blend of Trek continuity and medieval adventure, and further fleshes out her exploration of the Guardian of Forever. The explanation and resolution of the Guardian's malfunctioning was the sole downside of the book, falling into yet another Kirk-talks-all-powerful-beings-into-behaving trap, but as this is a relatively minor portion of the story, it's not an unforgivable lapse.
