Forbidden Flames is the third and final book in the Sinister series, a dark romance built on forbidden attraction and power plays. It can be read as a standalone, but readers will understand the characters and their choices more fully if they’ve read the first two books.

Author’s Note

This book is part of the Sinister series. While each story can be read as a standalone, this installment contains major spoilers for the previous books.

For the best reading experience, it is recommended to read the books in order:

1. Caged Love

2. Twisted Desire

3. Forbidden Flames

You can still enjoy this story on its own, but reading the earlier books first will provide deeper context and avoid spoilers.

Introdution

She spent her life trapped by expectations, her destiny chosen for her long before she found her own voice.

Then she met him, and obsession rooted itself before she could stop it. Running was her only escape, but even distance couldn’t extinguish the desire burning through her.

He has lived years haunted by scars that refuse to heal, until she storms into his life and pulls him from the darkness. When she disappears, his world collapses all over again. Now he’ll tear down everything in his path to bring her back.

Their fates were never meant to intertwine, but obsession doesn’t ask for permission.
