A fun romp

When it comes to the Ryan brothers, you can't expect plot heavy books. But there is enough plot to keep the book moving forward between spicy scenes and it's a decent plot.
If you took away most of the spice, from the first four books, you could probably make two books instead of four. But since the spice is fun (and when you have four partners, of course there's lots of spice), it's not so bad.
