Sparks by Wendy Higgins

At twenty-four, Harlow Robinson has run headfirst into a quarter-life crisis. Her high school girlfriends have dropped like flies, one wedding after another, forcing her into panic mode. It’s fight or flight time, and flight wins—literally. She breaks off a loveless engagement with her childhood sweetheart and abandons a teaching degree to become a flight attendant for Omega Skies.
Now Harlow is living her best glamorous, single life as a self-proclaimed sky muffin, at least that’s how it appears from the outside. But 3:00AM wakeup calls and nights alone in hotels make the days blend into a blur of loneliness. When her seven roommates sign her up for the dating app Sparks, Harlow finds herself navigating an entirely new lifestyle with more men than she can handle.
What’s a girl to do? Date them all, of course.
