The Handbook

For twenty-five years, Dean and Castiel have built a life together. They have three grown children, a new grandson, and every reason to believe they've earned their happily ever after. From the outside, they're the picture of the perfect family.

But appearances can be deceiving.

Dean has spent his entire life taking care of everyone else. He looks after his aging adoptive parents, Ellen and Bobby Singer, helped put his brother Sam through law school, raised three children, and now happily steps into the role of grandfather to little Oliver. Yet somewhere along the way, he lost sight of himself-and the husband he once couldn't imagine living without.

Castiel has always carried the responsibility of providing for their family. Driven, ambitious, and determined to secure their future, he's poured himself into his career at Knight Marketing, chasing a promotion that never seems within reach. As work consumes more of his time, the distance between him and Dean grows wider, leaving both men wondering when they stopped being partners and started living separate lives under the same roof.

When a surprising recommendation leads them to an unconventional therapist, Dean and Castiel are forced to confront years of buried hurt, unmet needs, and the painful truth that love alone isn't always enough.

Can they find their way back to each other before the life they've spent twenty-five years building falls apart?

Or has their greatest love story already reached its final chapter?
