Like a jewel shimmering in a Midwest skyline, the Toledo Institute of Astronomy is the nation's premier center of astronomical discovery and a beacon of scientific learning for astronomers far and wide. Here, dreamy cosmologist George Dermont mines the stars to prove the existence of God. Here, Irene Sparks, an unsentimental scientist, creates black holes in captivity. George and Irene are on a collision course with love, destiny and fate. They have everything in common: both are ambitious, both passionate about science, both lonely and yearning for connection. The air seems to hum when they're together. But George and Irene's attraction was not written in the stars. In fact their mothers, friends since childhood, raised them separately to become each other's soulmates. When that long-secret plan triggers unintended consequences, the two astronomers must discover the truth about their destinies, and unravel the mystery of what Toledo holds for them -- together or, perhaps, apart.
