This was a cute book. It had the "grumpy/sunshine" paring trope that was done very well. Greg was grumpy but he wasn't a jerk. He's just kind of shy and reserved. And Tasha is a ball of sunshine in general. I guess it's more of an Introvert/extrovert pairing. 

The "quickness" of their relationship progression made more sense because of their history. They were already in love at one point, and since they ended things mutually for school reasons, they still harbored feelings for each other. 

I remain on the fence if these books should be a little longer, or if their shortness is a good thing. I hope my library hold comes in soon, I look forward to reading the rest of the series.
