At twenty-seven years old, Andrew Wullaert received a phone call that changed everything.

A woman on the other end of the line introduced herself as his full-blooded biological sister.

What followed was a journey through questions he thought he had already answered.

Questions about identity.

Belonging. Family. Rejection. Gratitude.

And ultimately, who gets to decide what your life means after emotionally complicated things happen to you before you are old enough to understand them.

In Blood = Water: The Search for Identity Beyond Biology, Wullaert shares an unflinchingly honest memoir about growing up adopted, being reunited with his biological family, and discovering that reality is often far more complicated than the stories we tell ourselves.

Through humor, self-examination, vulnerability, and hard-earned perspective, he explores the emotional realities surrounding adoption that rarely fit into neat categories. The longing for connection. The fear of rejection. The need for agency. The tension between gratitude and loss. The realization that blood may explain where you came from, but it does not necessarily explain who you are.

What begins as a search for biological answers gradually becomes something much deeper: a search for identity itself.

This is not a story about villains and heroes.

It is not a story about blame.

It is a story about perspective.

About learning to live with unanswered questions.

About discovering that healing does not require perfection.

And about realizing that family is often built through commitment, sacrifice, love, and the people who choose to stay.

Raw, thoughtful, and deeply human, Blood = Water is for adoptees, adoptive parents, biological families, and anyone who has ever wrestled with the questions: Who am I? Where do I belong? And what truly makes a family real?
