    I was born and raised in the Big Apple by an Argentine dad and a Norwegian mom, speaking three languages at home. My love of languages and travel led me to move to Paris when I was seventeen with my grandmother’s cat – and I’ve barely stopped moving since. My other great love is all things Arthurian and I completed my PhD in Medieval Literature at the University of Cambridge before switching gears and heading to China to work as a journalist. I have held positions at the National University of Singapore and the University of Hong Kong, and in recent years have published several YA novels (the Sweet Black Waves trilogy and The Tesla Legacy) as well as nonfiction (The Myth of Morgan la Fey). I am currently based in London where I am engaged in a constant battle with my neighborhood foxes.

    With my diverse background, my tastes in books are equally eclectic. As an author myself, I am an editorial agent and enjoy polishing manuscripts until they shine like the top of the Chrysler Building! I am actively building my list in the following categories and particularly encourage submissions from BAME and marginalised writers.

    Interested in: Young Adult, Middle Grade, Fantasy, Science Fiction, Romance, and Non-Fiction.

    I joined Zeno at the beginning of 2020 after time served working for science fiction and fantasy imprint Gollancz, adult non-fiction publisher Icon, and almost every Waterstones bookshop London has to offer. My degree specialised in children’s literature with a dissertation debating what Young Adult fiction actually is. All of the above strongly influenced the kind of books I get excited about, as well as broader narratives that explore stories connected with LGBTQIA+, BAME, disability,  mental health, and other marginalised experiences.

    I’m particularly interested in submissions in the following areas: Fantasy, Science Fiction, Children’s, Graphic Novels, Non-Fiction.

    Essentially I’m a sucker for a good old plot-driven narrative. To break this down further, I like books in which things happen to people (or monsters, or aliens or whatever) – in which a character is faced with a problem and in which the meat of the novel is about them solving that problem. For me, good fiction is about forward momentum and the plot is the engine that should drive a story onwards. There are infinite variations and riffs on this classic approach and seeing them reinvented time and again is one of the great pleasures of reading.

    I’ll happily consider all kinds of fantasy and SF – but anodyne Tolkien derivatives will be given short shrift and I can spot ‘em a mile off!  I like cool monsters and heavy magic and I like books in which magic seeps into contemporary life. Neil Gaiman does this kind of thing beautifully but please don’t send me Gaiman derivatives either – be inspired by brilliant writers, but don’t try to replicate their work.

    I’ll read Urban Fantasy, but note that I’m not the ideal target demographic for this kind of stuff so I’m only looking for the highest quality material. Given the level of competition, anything less than exceptional will be bounced back to you. I’ll gladly read YA stuff – if you can ignite my sense of wonder, lost so long ago, buried beneath a black mountain of cynicism, then I’ll get the drinks in! And I’ll read space opera, horror, and thrillers and crime and historical fiction and combinations of all of the above – surprise me! And if it helps you further to target your submission, don’t send me political treatise disguised as fiction, or anything too whimsical or stuff that purports to be funny but isn’t. And read our submission guidelines!
