Bobby Brown is ready to share his story.

The singer, 46 – who was married to the late Whitney Houston for 15 years – will release an autobiography, Every Little Step, in June, he announced Friday.

“Writing this book has been a therapeutic process for me,” Brown shared with ABC News. “Getting it all out has allowed me to move on with my life.”

He is set to give a one-on-one interview about the book with ABC News’ Robin Roberts on 20/20 on Friday, June 10, the network said.

The book will hit shelves mere weeks before the one-year anniversary of Bobbi Kristina Brown‘s death. Bobby and Houston’s daughter died at the age of 22 on July 26.

Attorneys for Nick Gordon – Bobbi Kristina’s boyfriend who was raised as Houston’s son but never legally adopted – told PEOPLE at the time the results proved he “didn’t kill her.” However, in a wrongful death suit against Gordon, 20, Bobbi Kristina’s family alleges she “died due to a violent altercation” with Gordon and that he “injected her with a toxic mixture” – allegations Gordon previously denied.
