The Heavenly Sins trilogy is a set of three books about the same three characters, Tristan, Machidiel and Alastor. They should be read in order as the second and third books will not stand alone.
All three stories are ménage stories (MMM).
Books 1 and 2 were previously published with my former publisher. All three books are available from Pride Publishing.
Also available as a box set.
