Starting Again at Crofton Hall by Rebecca Cohen

After making a decision that will change his life forever, Robin Flint arrives at Crofton Hall, looking for a place to recover and start again. Love is not enough to continue living a lie.
An unexpected meeting where sparks fly was meant to be a one off, but Simon MacLove is just too wonderful to cast aside. But since Robin hadn’t intended to continue things, Robin didn’t tell Simon, a local police officer, that he was a millionaire trust fund baby and the future Viscount Whetford. Robin has a lot of baggage, but so does Simon, and whether they can carry it together and is very much up in the air, especially as Robin’s now ex-boyfriend, movie star Dorian Marsten, hasn’t accepted things are truly over between them.
Meanwhile, Ben and Ashley are still enjoying their post-honeymoon bliss, and have decided to work on the next generation of Redbourns. Only it’s not so easy when neither of them have the necessary biological equipment, meaning the road to them becoming parents isn’t going to be straightforward.
