The long-time couple, who rose to fame as teenagers on MTV, have penned an autobiography detailing the birth of first daughter Carly, their decision to have her adopted and how they've remained a strong unit over the years.
Catelynn and Tyler were first introduced to the public on 16 & Pregnant, a groundbreaking documentary that filmed several teenage parents-to-be, showing the realities and struggles of becoming a parent so young.
In Catelynn and Tyler's case, they decided to place daughter Carly up for adoption as they felt it was in her best interests.
Their story, which continued in Teen Mom, showed Catelynn and Tyler's contact with Carly's adoptive parents and their updates on Carly's life.
A description of the book on Amazon.com reads: "Between their experience placing their first daughter for adoption, and their struggle to cope with problems in their families, Catelynn and Tyler were challenged in every imaginable way.
"But against all odds, the childhood sweethearts rose above the dysfunction to become responsible adults whose story has inspired many others."
