Study in Drowning

Effy has always believed in fairy tales. Since childhood, she's been haunted by visions of the Fairy King. She's found solace only in the pages of Angharad - a beloved epic about a mortal girl who falls in love with the Fairy King, and then destroys him. Effy's tattered copy is all that's keeping her afloat through her stifling first term her prestigious architecture college. So when the late author's family announces a contest to design his house, Effy feels certain this is her destiny.

But when Effy arrives, she finds Preston Héloury there, a stodgy young literature scholar, who is studying Myrddin's papers and is determined to prove her favourite author is a fraud. 

As the two rival students investigate the reclusive author's legacy, piecing together clues through his letters, books, and diaries, they discover that the house's foundation isn't the only thing that can't be trusted.
