This had been recommended to me some time back by purplepooka, so that's the second good tip from her that I have followed up this week.
I enjoyed it. The amnesiac Eighth Doctor, with companions Fitz and Anji (who I previously encountered a few books later), is on an artistically inclined colony world where the indigenous large tiger-like fauna turn out to be more intelligent than their human neighbours had thought. Multiple narrative points of view, both human and tiger, vividly and credibly portrayed background scenery, and a very Doctor Who-ish, humanistic resolution to the conflict between the two races. Will look out for more by this author.
