Of Shadows & Secrets 7-Book Bundle

This bundle includes personally autographed paperbacks of all seven novels in the exciting romantic mm spy thriller series, Of Shadows & Secrets. This is Casey's most award-winning, critically acclaimed series, with 2 gold, two silver, and one bronze in international literary competitions.

Of Shadows & Secrets is a slow‑burn M/M romance wrapped in a high‑stakes, historical spy thriller.

The romance in Of Shadows & Secrets is a deeply emotional, slow-burn M/M love story set against the high-stakes world of wartime and Cold War espionage.

At its heart is the enduring partnership between Will and Thomas, two young American operatives who fall for each other during their training at Harvard in 1941. Their relationship unfolds gradually, marked by stolen glances, coded notes, and quiet intimacy—all beneath the constant threat of discovery in an era where their love is dangerous, even criminal.

This is not a typical romance—it’s forged in fire. Across many books, their connection grows from the tentative beginnings of first love into a powerful, soul-deep bond that sustains them through betrayal, loss, moral compromise, and the violence of war. There’s passion, yes—but also trust, devotion, and the raw vulnerability of two men who find in each other a rare kind of safety in a world built on secrets.

Their romance isn't just subplot—it is the emotional spine of the series. Every mission, every close call, every hard choice is made more human—and more harrowing—because of the love they share.

For readers who crave romance that’s earned through adversity and rooted in loyalty, Of Shadows & Secrets delivers an unforgettable pairing that lingers long after the final page.
