After being diagnosed in her early 30s with terminal breast cancer, Heather McManamy felt like her life was crumbling. Her "normal" vanished and was replaced with multiple surgeries and dozens of chemo treatments that could briefly extend her life but would not prevent her inevitable death. With an effervescent spirit and a new perspective, Heather started to live each day as if it were her last. She learned to soak in the moment, appreciate the beauty around her, and celebrate her blessings. She also pondered her daughter's future journey without her mother and gracefully prepared for it.

Heather began to write greeting cards to Brianna. Cards for her first day of school, her 16th birthday, her wedding day. Cards for when things were going right and when they were going wrong. Cards for when Brianna would need her mother - whether in five years or in 50 years - and Heather wouldn't be able to be there for her.

Cards for Brianna is the story of one mother's powerful love for her young daughter, and Heather's unmatched experiences, laced with laughter and charm, are a reminder to never take a single day for granted.
