About

Katie Ferriello is the newest agent to join the Mansion Street Literary Management team. Her focus is on romance and fantasy, as well as children’s fiction. She particularly loves fantastical worldbuilding, deeply emotive characters, and strong voices.

Katie earned her BA in English from Manhattan University and a M.Ed. from Fordham University. Motivated by her love of reading, she taught middle school English for sixteen years. Later, her passion for books and business led her to intern at multiple agencies. Grateful for her English degree, business experience, and contract/negotiation knowledge, she is excited to apply those experiences to helping writers navigate their literary careers.Though born in New York, she currently lives in Utah where she spends her free time camping, mountain biking, and skiing.

Agent Impersonation Scams are becoming commonplace.
A legitimate agent will not contact you and request money to represent you. Never pay an agent an up-front fee. That is not how literary agent representation works. Agents earn a commission only after they've landed a publishing deal for you. Also, agents scarcely ever contact writers. If an agent that you haven't queried contacts you about representation, be suspicious. Look up the agent and check if the email address is correct for that agent/agency.
