Can You Keep a Secret?

by Mary Monroe

2016

This prequel novella finds teenage best friends Lola and Joan chafing against messy, watchful families and craving independence. Their first shared schemes with boys and money plant the seeds for the risky choices that will define the Lonely Heart, Deadly Heart series.

Series background & context

The Lonely Heart, Deadly Heart books follow two best friends, Lola Poole and Joan Proctor‑Riley, whose search for excitement and affection leads them into increasingly dangerous territory. On the surface these are stories about online dating gone wrong. Underneath, they’re about loneliness, envy, and the cost of ignoring red flags.

In Every Woman’s Dream, we meet Lola and Joan as teenagers running a risky mail‑based scam, writing fake love letters to older men for money. Years later, both women are stuck in disappointing adult lives—Joan with a selfish husband, Lola with demanding relatives and old emotional wounds. They turn their old hustle into a modern game, using dating sites to line up wealthy, no‑strings lovers.

Their adventures feel glamorous at first: gifts, trips, and constant attention. But the thrill is addictive, and soon both women are taking greater risks to keep the high going. The men they choose are not always honest; some are just as calculating as Lola and Joan, and far more dangerous.

A pivotal figure is Calvin Ramsey, a long‑haul trucker who seems like the answer to Lola’s dreams. He’s kind, attentive, and eager to provide. What she doesn’t know is that he enjoys controlling and destroying women. As the series moves through Never Trust a Stranger and The Devil You Know, Calvin’s presence turns their game into a nightmare.

Shorter works like Can You Keep a Secret? flash back to Lola and Joan’s younger years, filling in how their families, early scams, and half‑kept promises shaped the women they become. Those glimpses make their later choices feel more tragic than simply foolish.

The tone here is brisk and suspenseful, with plenty of sex, gossip, and sharp dialogue. But Monroe also pays attention to the emotional fallout: the way betrayal hardens people, how money can twist relationships, and why some friendships survive even when they probably shouldn’t.

If you like domestic thrillers built around complicated women, high‑risk schemes, and moral gray areas, starting with Every Woman’s Dream and reading straight through gives the fullest impact of this series.
