The Readymade Thief by Augustus Rose
An unlikely but likable heroine betrayed by family and friends, the creepy secret society pursuing her, and Marcel Duchamp's most famous piece of art (see below) all converge in a story that will keep you riveted until the last page.
The Readymade Thief is completely original from start to finish, and I highly recommend it.
The artwork is The Bride Stripped Bare by Her Bachelors, Even by Marcel Duchamp. It is a VERY abstract sculpture at the Philadelphia Museum of Art, and I found it helpful to refer to a site the author recommended in his acknowledgements:
