Phillips' version is a little different. Three sisters, adopted by a bachelor uncle when they are orphaned (parents die in plane crash), grow up to work for/with him in an agency. They are used to hanging out with the pro-ball players and sometimes even date them, usually in a disappointing sort of way. So we know we're in for at least a trilogy. _Hot Stuff_ is entry one, about Annabelle, the oldest sister who had to be Perfect and Keep Everyone In Line so that bachelor uncle would not give them up for adoption which would inevitably involve separation.
She's helping out a retired player who is opening a lodge and summer camp operation. He is dyslexic and wants to Help Out Challenged Young 'Uns. His parents were not sympathetic to the learning problems and do not care at all about his Accomplishments (like, a couple of times to the SuperBowl). Someone is sabotaging the lodge; she's doing PR damage control. They're trying to put a stop to the sabotage, so there's a bit of a mystery.
It's not bad, but it's no SEP. A lot of the conversations are a little clunky -- these people are awfully articulate and have amazing insight into their own psyche and the psyches of those around them. It's more than a little bit too pat.
That said, a pleasant enough read. If it sounds like the kind of thing you might like, it would probably be quite painless. I got it through a swap site and may pick up the sequels.
