I had never heard of the Company series until I saw it on a list of time travel novels. Mendoza is saved from the Spanish Inquisition, turned into an immortal and sent on her first mission in medieval England. I got vibes of The rise and fall of DODO and St. Mary's, only less comical, but the book is older. Mendoza is immortal, but only 19, and has a lot to learn. Love, for example. I'm looking forward to book 2.
