Born in the South of France, Gaëlle now lives near big city Lyon. Early, she developed a passion for the English language and the USA, which she often visited. The TV show Buffy the Vampire Slayer sealed those two passions in written words when she began writing fan fiction. She wrote over 70 fanfiction pieces over the course of 6 years before finally leaving the safety net that it had become.
Her first novel, When the River Flows out of its Bed, was released in 2011, followed a year later by Legacy, a 500,000 word urban fantasy under the pen name GC Lehane. Fire and Ice was released in 2014. One Breath at a Time came out one year later in May 2015 and That Week in Acapulco followed in December 2015. A Little Bit of Grey was released in the spring of 2016 and Three to Tango in 2020. A new urban fantasy Endless War comes out in March 2021, and a new romance What Happened Next is due in Spring 2021.
From 2016 she began translating her novels in French, her native tongue.
A lover of animals, outdoors and music, Gaëlle takes long walks through country paths and spends the rest of her time petting her many cats.
