Homebound by Alyssa B. Cole

Abby Doyle is perfectly fine without a soulmate. Her parents have matching soulmate Marks and their marriage definitely isn’t great, so she’s content living Markless with her boyfriend in New York. Sure, she might have slight self-esteem and anxiety issues, but hey, she’s getting by.
Until she receives a Mark, and he doesn’t.
After that devastating blow, Abby returns to her hometown of Lake Redwood, Minnesota. There she reconnects with her older sister’s best friend, Ethan Perry – who also happens to be Abby’s childhood frienemy and middle school crush. He’s annoyingly wonderful, and still out of Abby’s league. And apparently, he is also Marked.
Can Abby find a place where she belongs and allow herself to be loved?
