Terry's debut novel Becoming Nancy was published in 2012. Described by The Independent as "a deliciously camp rites of passage novel", the book was shortlisted for The Polari First Book Prize. In 2013, Tony-winning director Jerry Mitchell (Kinky Boots, Hairspray) bought the rights to commission a musical adaptation of Becoming Nancy, which had its world premiere at the Alliance Theatre in Atlanta in 2019. Terry has since joined the creative team, writing seven new songs for the 2024 UK premiere at The Birmingham Rep along with Elliot Davis and George Stiles. The updated version of Becoming Nancy played to nightly standing ovations, receiving four and five star reviews across the board.
