Fifty years ago, Ravi Gupta left someone behind. Now she has found her way home. Professor Ravi Gupta has spent a lifetime guarding the portal he opened as a young man, through magic he never should have touched, and the world of peril on the other side. But the passage is not his darkest secret. That is the woman he left there, and never spoke of again. When his most brilliant student vanishes through the same door, Ravi has no choice but to go back. He returns to that hostile realm to bring the boy home, and finds the world beyond ruled by the research associate he and his partner marooned there decades ago. She has not forgotten what they did. And when the passage opens once more, she follows him through it, into the heart of the college he loves, hunting the man who abandoned her. To save his students, Ravi must at last answer for the betrayal he has spent fifty years trying to outrun. Legacy of Shadows is the third novel in the Cambridge Gothic series. Atmospheric, warm-hearted dark academia steeped in the real Cambridge, it is the culmination of the trilogy, for readers who love Ben Aaronovitch's Rivers of London and Jodi Taylor's Chronicles of St Mary's .
