Working with philosophy professor Ian Walker, architect Ruby Foster couples her architectural and engineering training with a natural talent for forensics to solve lethal building collapses disguised as structural accidents.
When a mall unexpectedly collapses, killing more than two hundred people, its structural engineer is found dead in his bathtub the night before he’s set to testify at the inquiry. His roommate and best friend, architect Ruby Foster, believes he was murdered and sets out to find answers. Philosophy professor Ian Walker survived the collapse that took both his wife and his mobility, and only wants to find the bottom of a scotch glass. Ruby pulls him into her quest, and together they discover that they have two days to find the reason for the collapse in order to prevent another.
Ruby Foster’s first experience teaching architecture studio is a disaster – literally. The prototype walkway designed by her students collapses during its unveiling, killing and injuring dozens. When the authorities turn to her for answers, she teams up again with Ian Walker to reveal a revenge plot risen from the ashes of a tragic past.
