Fifty Shades of Gay — Ryan Field

In this third novel from the Chase of a Lifetime series, Jim Darling and Len Mayfield are picking up the pieces in the wake of Cain Mayfield's tragic death. While Jim is busy working on a new marketing plan for Carol Greene's medical marijuana dispensaries, Len is trying to figure out ways to get Jim to experiment with BDSM.
Though Jim Darling misses his best friend Cain so much it hurts, he's willing to do anything to please his husband…a husband who suddenly seems like a different person Jim can't figure out.
After a terrible scare that involves bees and their toddler son, Culum, they get a phone call from Len Mayfield's estranged mother in Connecticut that changes their lives forever. For the first time since Jim had known Len, he finally meets the family Len has refused to talk about and Jim is in for more than a few surprises.
With all the original characters from previous books, Jim and Len wind up rediscovering their relationship. Jim also discovers there are more than a few shades of gay and he has to figure out how to deal with them on his own terms. Will the next tragedy they face bring them closer or pull them apart? And will Jim ever come to terms with the things his husband expects him to do?
