Callen has recently joined The Good Literary Agency as their Submissions Coordinator and interim Agency Assistant, aiding the team across all departments and acting as the initial reader for submissions.

In 2019 he graduated from Bath Spa University’s MA in Writing for Young People, becoming the first care leaver in the history of East Sussex to study at postgraduate level.

Alongside his work for TGLA, Callen reads for publishing houses that specialise in Children’s and YA fiction and is a Manuscript Assessor for Faber Academy.

His long-term goal is to become a literary agent, known for always having ice cream on standby, ready to celebrate his authors’ successes. When not working, he spends his spare time writing Contemporary YA fiction – his current Work In Progress being an #ownvoices novel about growing up in foster care.
