Look, the Between-the-Numbers books are vaguely fun. But they're also totally weird in that it takes a well established crime/chick lit series and reinvents it as tangentially paranormal. It also basically turns the existing love triangle into a love square with the addition of Diesel to Steph's List of Guys Who Randomly Appear In Her Apartment, and NO THANK YOU PLEASE.
This one made MARGINALLY more sense than Visions of Sugar Plums, in that it's basically Steph being roped into helping a bunch of people have a good Valentine's Day. It was fine. But it was also nothing special or particularly memorable. So. There's that.
