Liseanne Miller is the President & CEO of Global Lion Intellectual Property Management — a boutique agency with a half-century of Hollywood DNA — who seeks commercially minded authors across virtually every genre, with a particular eye for film/TV crossover potential and underrepresented voices.
In brief
Liseanne inherited Global Lion from her late father Peter Miller, the original 'Literary Lion,' and took the helm in September 2021 — the agency's entire 50-year client roster and Hollywood relationship network came with her, giving a newer CEO rare institutional muscle.
The agency's legacy client list skews heavily toward true crime, legal thriller, and narrative nonfiction (Vincent Bugliosi, Nancy Taylor Rosenberg, Jay Bonansinga), signaling that deal-making experience in those categories runs deep — even if Liseanne personally names crime fiction as a leisure pleasure rather than a pitch priority.
Film and TV crossover potential is not a bonus — it is a core selection criterion. Global Lion has worked with Warner Bros., Paramount, Disney Channel, CBS, and Showtime; a project with screen adaptation upside will genuinely stand out here.
The agency demands exclusive submissions: do not query while the manuscript is under consideration anywhere else.
Liseanne explicitly wants authors who are prolific or planning to be — a one-book-and-done pitch will land with less enthusiasm than a pitch that names the series or the next project.
Lately
Liseanne assumed the role of President and CEO of Global Lion in September 2021, continuing the agency her father Peter Miller built over five decades. She has indicated she is actively building a new generation of clients alongside preserving long-standing relationships.
What Liseanne is looking for
Upmarket and commercial adult fiction with broad audience appeal is a stated priority. Liseanne is drawn to character-focused stories and cross-genre work that could translate to screen. Crime fiction and psychological thrillers align with her personal reading tastes, and the agency has deep legacy roots in legal and crime narratives.
The agency's historical strength — including representation of Helter Skelter author Vincent Bugliosi — makes this a category where Global Lion has genuine editorial and deal-making depth. Liseanne lists true crime as a personal favorite and it appears repeatedly in her stated interests.
Liseanne cites the late Sir Ken Robinson (a former Global Lion client) as a personal touchstone, signaling appetite for big-idea nonfiction by experts with platforms. Books in health, wellness, mind/body/spirit, pop psychology, and business are all explicitly named as active categories. Authors who are or can become recognized voices in their field are especially welcomed.
Commercial and literary YA — including fantasy YA — is listed as a sought category. Liseanne's interest in diverse voices (LGBTQ+, BIPOC, Latinx, South Asian, underrepresented perspectives) makes YA with those threads a natural fit. Middle grade is noted but less emphasized.
Inspirational memoir and biography — particularly stories from underrepresented communities or that carry a message of positivity or uplift — fits Liseanne's stated editorial philosophy of asking whether a book makes the world a better place. Authors with existing platforms will have an advantage.
Genre fiction including fantasy and science fiction is explicitly listed in the agency's active submission categories. The emphasis on film/TV potential means high-concept, commercially oriented SF/F with adaptation hooks is a stronger fit than purely literary or niche genre work.
Given the agency's deep Hollywood relationships — Warner Bros., Paramount, CBS, Showtime, Disney Channel among past partners — 'making of' books and industry narrative nonfiction sit in a genuine sweet spot. This is a category few agencies name explicitly; Global Lion does.
Art history, illustrated books, and food writing are listed as categories the agency accepts. These appear to be welcomed rather than actively hunted — pitch with strong platform and production vision.

How to query Liseanne
Send to the agency's dedicated query email address (queriesgloballionmgt@gmail.com as listed publicly on the agency site) — do NOT query Liseanne's personal agency address for new submissions.
This agency requires EXCLUSIVE submissions. Do not send the manuscript or proposal to any other agent while it is under consideration at Global Lion. Violating this is likely disqualifying.
Submit only one project at a time per author, even if you have multiple manuscripts ready.
Your query package must include: (1) your full name and single preferred email address, (2) a standard query letter with title, genre, word count, and target audience, (3) approximately 20 pages of a sample chapter (a chapter synopsis is acceptable if a sample chapter is unavailable), and (4) a short author biography.
Optionally include links to your social media profiles or author website — Liseanne values authors with a marketing mindset and an existing or developing platform, so a strong online presence can only help.
Lead with the film or TV potential of your project if it exists. Global Lion's Hollywood relationships are genuine and this is an active filter, not a marketing afterthought.
Signal your prolificacy or pipeline: mention the next book you are working on, or frame this as book one of a series. Liseanne has explicitly stated she wants authors who are prolific or planning to be.
Frame your book's real-world impact or perspective: Liseanne's editorial filter includes asking whether a book entertains, educates, uplifts, or represents an otherwise underserved voice. Give her a one-sentence answer to that question in your query.
Be patient after submitting — the guidelines note that response times may vary and ask writers not to follow up prematurely.
