ANNOUNCING: The Girl Who Was Tuesday

Hear ye, hear ye—Diachroneity Books is ready to bring forth the third of its literar offerings: The Girl Who Was Tuesday by Beatriz Seelaender.

Mariam Grubbs is a different person every day of the week. Literally.

To manage her unusual condition, the weekly counterparts sharing her body need to keep proper records of their memories and appointments. Everything changes, however, when Tuesday (the responsible one) gets a call from Scotland Yard about a missing person. As she struggles to piece together what happened to one of the Days’ missing friends, only one thing is certain: Her co-pilots have been keeping vital—and deadly—information from her.


Available 16 June 2026 in paperback and ebook. Whee!
