After a heartbreaking public breakup, Millie learned to keep to herself and never share her true feelings. Instead, she vents her thoughts into emails that never leave her drafts folder. When all her emails are accidentally sent, Millie must deal with the chaos that ensues after her colleagues, friends, and family find out her deepest confessions.

Lia Louis has penned an adorable and lighthearted romance with a relatable protagonist. Millie's self-doubt and constant people-pleasing were all too realistic. As was her awful ex that you wish she'd realize wasn't good enough for her. With the public embarrassment of having everyone hear her unfiltered thoughts to her struggle to be open and vulnerable with a new romantic interest, Better Left Unsent was a well-written, heartwarming, feel-good read.
