Sienna & Jakob — Thayer King

The year is 2100. Wise people marry by registering with Bioexpa Data Match. The matchmaking company has such a near perfect record that choosing your own mate is now considered tantamount to marrying a blood relative. Recently paired, Sienna Bloom and Jakob House have known each other since they were teens. She's his sister's best friend. Sienna's been awaiting her perfect mate since she signed up with Bioexpa at the age of eighteen. She's thrilled when she's paired with Jakob. There's only one problem. Jakob's in love with another woman. Jakob only signed up with Bioexpa to make his girlfriend Ella happy. When he returns to his hometown, it's with the intention of settling down with Ella. But then he's matched with Sienna through Bioexpa and his plans fall apart. He's not one to ever break a promise, but he can't deny the pull he feels towards Sienna.
