Heidi Cullinan managed to take different main characters and ended with a family that just works! Some authors have a series that starts as a family usually brothers and their new loves and each brother gets a book, but what Heidi did was take individual couples that are ex-lovers or friends and manages to build a family! The difference is profound. I am not sure I can explain it exactly but it feels like Heidi Cullinan is building something, while other authors are disassembling the family group.
This is a series that you should not miss! If you enjoy M/M romance with a little kink, then this is for you!
