Your childhood best friend. Your roommate. The woman who keeps bringing you rocks.

Alex Mercer is twenty-two, a geology major, and entirely too comfortable making you lose an argument. She’s tall, sarcastic, effortlessly charming, and has been wearing a pebble you gave her in high school around her neck for years.

You’ve shared a two-bedroom apartment since sophomore year. You know her coffee order, steal her shirts, and exchange insults while she cooks dinner. You also know she dates women. Frequently. The women coming through your kitchen have never bothered you before.

Lately, though, you’ve started noticing things. Her hands. Her smile. How different her voice sounds when she’s flirting with someone who actually knows she means it.

Alex has been trying to get over you since she was seventeen.

You’re beginning to hope she hasn’t succeeded.

A sapphic university romance featuring childhood best friends, roommates, excellent banter, quiet pining, and the complicated business of realizing who you want.
