A story of triumph over adversity, the strength that can be found in love and kindness, and the power of one couple to effect positive change in the world.

Rachael and Jonathan were thrilled to welcome their baby Mackenzie into the world and to start their new lives as parents. Little did they know that in a few months that they would be tested to endurance and beyond.

Like many other couples starting a family, Rachael and Jonathan had no idea they were both carriers for a genetic disease, and that 1 in 20 babies are affected by genetic birth defects. Their daughter was one of those babies, and Mackenzie's Mission is Rachael's beautiful and heartwarming account of Mackenzie's life, child loss, and a journey through IVF.

Determined that other couples should not go through the same heartbreak, Rachael and Jonathan are now champions for genetic testing.

This is a story of triumph over adversity, the strength that can be found in kindness and the power of one couple to affect positive change in the world.
