Tyler began writing professionally in the 1990s selling stories to Penthouse Variations and Playgirl. Her first novel was published by Blue Moon when she was 23. Tyler went on to write twelve novels for Masquerade Books before moving to Virgin Books' Black Lace and Cheek imprints in 1999.

Tyler writes in an intimate, semi-autobiographical style, focussing on themes of female submission, spanking, bondage, bi-sexuality and group sex. In August 2006, Tyler began blogging intensely about a former BDSM relationship, described by The Guardian as "a sulphurous personal memoir of past sexual activities which put Belle de Jour's timid exploits in the shade." Initially intending to write confessionally each day for a month, Tyler continued with her story for 16 months, gaining a broad and loyal daily readership.

Described as a "trollop with a laptop" by East Bay Express, Tyler continues to blog regularly, using the platform to engage with readers, and to promote emerging Writers by showcasing their work in competitive "Smut Marathons". In 2013, the first in a trilogy of novels based on Tyler's diaries and personal blog entries is published. Billed by the publisher, Cleis Press as a "work of autobiographical fiction, a meta-novel with reality at the core", Dark Secret Love: A Story of Submission takes its title from the william Blake poem, The Sick Rose.
