Blissfully Undone by Red Phoenix is a contemporary romance. This book does have menage sex scenes so it may not be for everyone. Ms. Phoenix has delivered a well-written book. The characters are outstanding. Jenny and Dan have been friends and ride to Dan's mountain cabin to meet up with their boyfriend and girlfriend for a week. A blizzard keeps them stranded before their partners arrive. This story has unexpected twists and turns all the way through, it really keep readers wrapped up in what will happen next. I enjoyed reading Blissfully Undone and look forward to reading more from Ms. Phoenix in the future. Blissfully Undone is books 1-4 of the Blissfully Series and can be read as a standalone. I am glad I read this book instead of individual books because I'm not a fan of cliff-hangers and my guess is that the individual books would have been cliff-hangers. This book is complete though, not a cliff-hanger.
