Melanie Laidlaw and Menachem Dvir meet at a series of international conferences where jet-setting scientists come together to discuss the global implications of their discoveries. Melanie runs a foundation that awards grants for innovations in reproductive technology; Menachem is an infertile nuclear engineer and a married man. Naturally, they fall in love.

What follows is a story of sexual steam, stolen seed, and religious conversion -- a very modern romance that hinges on a cutting-edge scientific breakthrough. As Melanie and Menachem discover, what science makes possible, only two hearts can make right.
