This Christmas, Amy is getting what she wants. Her career in fashion design is taking off. Her boyfriend Brad is the dictionary definition of a catch. Soon he'll buy the massive diamond that makes it official: she's nobody's hard luck case anymore.

When Amy throws away everything she's worked for with one impulsive, impossible word, she's horrified she's proved Jon right...and strangely, secretly excited. That he knows more than the past she wants to forget — he knows what heats her up, what makes her heart race.

But remembering what she's forgotten since last Christmas might mean breaking all the rules...
