This is a fascinating book. I don't think I have ever read anything else quite like it. Lisa is a middle aged business woman with her best friend Paula. But a trans woman still in the process of transitioning. As a man, she'd had two wives and now has two grown up children who are having trouble accepting Dad as Mum. This story would be fascinating enough, but exhausted on a business trip she makes a spur of the moment decision to take a few days off on Hawaii, where she meets and falls in love with Dana. The feeling is well and truly mutual but although I won't give too much of the game away, what gender is Dana? And ultimately, does it matter. If you enjoy having your mind opened, you'll love it.
