Unsolved

One summer. One deal. One woman he never saw coming.

Cassandra Berry never expected to land a deal that could change her entire life. A life-changing amount of money and a spot at any college of her choice-all in exchange for one outrageous mission: seduce a man, get pregnant, and disappear. It sounds like the perfect plan. Easy. Clean. No strings attached.

Until she meets him.

Harry Xavier Devon is not just any man. He's a mathematical genius, a global sensation, and the proud bearer of two Millennium Prizes. Revered as the next Newton, he's a man who can calculate everything-except betrayal. So when his own brother tries to use Cassandra to trap him into fathering a child he physically can't have, Harry sees the scheme coming a mile away.

But instead of blowing the whistle, Harry flips the game.

He offers Cassandra double the money to pretend the plan is working-fake the seduction, fake the intimacy, fake the pregnancy. All to humiliate his brother. To finally take control.

Yet not everything goes according to formula.

Because Cassandra isn't the gold-digging, naive girl Harry thought she was. She's clever. Fiery. Unexpected. And she has secrets of her own.

Living under the same roof for one long, sultry summer, the lines begin to blur.

The numbers stop adding up.

And for a man who's always trusted logic over instinct, Harry is about to discover that some variables-especially the human kind-refuse to be solved.

What begins as a calculated arrangement soon spirals into something neither of them saw coming.

Because love?

That's the one equation you can't control.

A slow-burn, enemies-to-lovers romance packed with wit, chemistry, and emotional depth. Perfect for fans of sharp banter, morally gray motives, and characters who are anything but predictable.
