I feel that both of these sisters, especially Josie, who was hugely likeable in all of the previous stories, deserved their own romances outside of the "friends of family" circle.
It feels a bit like a TV Soap Opera where the same people just keep changing partners and switching spouses, with very little new blood.
I also thought both of these matches were forced and contrived out of very little foundation in the previous stories. It was disappointing given that I really loved the first two books, especially Kiss Me Annabel.
I generally am a huge fan of series with different friends or siblings getting their own stories, but it need not be so forced, both Maitland and Josie deserved better.
