Kendall Devin is either too much or not enough-it depends on which of her recent boyfriends you ask. Fed up with relationships, she dives into the world of casual Tinder hook-ups instead. She's horrified to discover the man she's been sexting for the past week is the father of one of her kindergarteners. Mason Reed recently gained full custody of his daughter, Finley, and moved back into his overbearing parents' house. He has no time for relationships-and he especially doesn't need any added drama in his or Finley's lives. So while Kendall has caught his eye, he knows getting romantically involved with his daughter's teacher is a bad idea. The two attempt to forget about their connection, but with Mason volunteering at school at every given opportunity, that proves to be difficult. Not even planning the school's fall festival can distract Kendall from Mason's flannel-wrapped charm. And the more they're together, the harder it is for either of them to resist temptation. Mason is the first man who makes Kendall truly feel seen, and he can't stop imagining her becoming part of his family. To him, she's perfect. But how could this possibly work?
