Un-Friend by Heather Lauren

After a one-night stand with the last man I should have been tangling sheets with, I swear off men and dating all together. Until those two pink lines show up and flip my world upside down. I thought I would never see the devastatingly sexy jackass again and I do everything in my power to plan my future as a single mom.
When my besties plan a road trip to Las Vegas to celebrate their upcoming wedding, the plan is to let loose a little and leave my stress behind. But the trip gets a bonus guest and I’m faced with a decision I thought was already made. Now I have four hundred and sixty-nine miles to figure out how to tell Derrick he’s going to be a dad.
