Never fall for your best friend.

That's the rule. The code.

Claire Harlow always follows rules-except this one.

However, when an attack leaves both of their worlds shaken, she decides to walk away from what could have been and hide within her own shadows.

Kingston Montgomery is the man who saves the day.

At least that's what he's always told himself-until one day he was too late.

Now he's trying to find his purpose while also ignoring the heat between him and Claire.

When a chance blizzard changes their plans, one night turns to two...and then there's no going back.

Only the two must overcome what they thought their relationship should be and realize what it could become. Because if they don't figure it out quickly, the spark that ignites them could burn them both.
