The Mysterious Composition of Tears (Hardcover) (ISBN-13: 9781950750467)

After a series of climate calamities, physicist Fleur Robins takes off for deep space in a desperate attempt to save the species from extinction. During her mysteriously prolonged absence, the internet has crashed, fire and flood have devastated whole countries, and End of Times cults have proliferated. There have been some intriguingly hopeful changes, too-nanoparticle holograms have replaced electronic devices, young people are witnessing exquisitely colorful "Shimmers," and the most gifted of them converse regularly with animals and trees.

While Fleur's distraught husband Adam leads their Caltech physics team in frantic efforts to pinpoint her whereabouts, and Fleur herself plots her return home, their teenaged children Callay and Wolf fall in love with surprising partners. But when the charming son of an End of Times pastor crosses Wolf's path during a particularly vibrant Shimmer, events are set in motion that will upend everyone's life and transform planet Earth itself.

This latest installment of Sharon Heath's saga of the quirky Nobelist Fleur is simultaneously a vision of what awaits us in a post-Covid world, a wild romp through quantum reality, and a deep sea dive into the dark and light vagaries of the human heart.
