Quirky, original, and a little bit batshit, Beatriz Seelaender’s delightfully obfuscating novella is a chaotic meditation on identity, autonomy, and individuality set against a veggie-based murder mystery where the reader is always, deliberately, one step behind.

Mariam Grubbs is Tuesday. Not Monday, Wednesday, or Thursday through Sunday. Just Tuesday.

To keep track of their day-to-day lives, Tuesday and her six other selves must maintain an open and honest line of communication through whiteboard messages, and not a little bit of private notes and coded games of chess. So what happens when Scotland Yard comes knocking—a dead friend on their books and Mariam looking like the prime suspect? A whole lot of chaos, manipulation, and a magical mystery tour of London as Tuesday, always the responsible one, tries to solve the case of which Day dunnit and why.

A fantastically obscure tale of self- and/or sisterhood, The Girl Who Was Tuesday takes an absurdist look at the concept of individualism from the perspective of someone who is anything but.
