Good Morning America host Robin Roberts had a very rough year in 2012 and she plans to share her story with the world. 

Roberts will write a memoir about the life-threatening blood disorder she battled with, the Good Morning America co-host announced on Wednesday. Her story will be published under Grand Central Publishing and will be released next April. 

The upcoming memoir will be her second book. From the Heart: 7 Rules to Live By was released in 2007 and made it on The New York Times best-seller list. In her second book, the 52-year-old will share details about the deadly disease she was diagnosed with, as well as discuss her recovery. The life lessons she learned while battling the illness will also be included in the currently untitled book, according to the story's publisher. 

Roberts was quoted in the publisher's announcement of saying, "I am humbled that many have an interest, and draw strength from my on-going journey." Following a congratulatory tweet from CNN and ABC News contributor Donna Brazile on Wednesday, Roberts wrote on Twitter Wednesday, "YOU inspire me." 

After beating breast cancer five years ago, Roberts was diagnosed last year with myelodysplastic syndrome (MDS), a bone marrow and blood disorder.

"I received my MDS diagnosis on the very day that Good Morning America finally beat the Today show for the first time in 16 years. Talk about your highs and lows!" she wrote in an open letter published on ABCNews.com.

The GMA co-anchor underwent chemotherapy and later received a bone marrow transplant using her sister's match, which helped her return to the ABC show in February. 

On May 20, Roberts, who has been very vocal about her disease, tweeted, "Just realized I'm technically 8 months old today! My bone marrow transplant was 8 mon ago. Thrilled my sis (aka fab donor) is with me in NYC."
