The Chemical Garden Trilogy, Book 1

By age sixteen, Rhine Ellery has four years left to live. She can
thank modern science for this genetic time bomb. A botched effort to
create a perfect race has left all males with a lifespan of 25 years,
and females with a lifespan of 20 years. Geneticists are seeking a
miracle antidote to restore the human race, desperate orphans crowd the
population, crime and poverty have skyrocketed, and young girls are
being kidnapped and sold as polygamous brides to bear more children.
When Rhine is kidnapped and sold as a bride, she vows to do all she
can to escape. Her husband, Linden, is hopelessly in love with her, and
Rhine can’t bring herself to hate him as much as she’d like to. He opens
her to a magical world of wealth and illusion she never thought
existed, and it almost makes it possible to ignore the clock ticking
away her short life. But Rhine quickly learns that not everything in her
new husband’s strange world is what it seems. Her father-in-law, an
eccentric doctor bent on finding the antidote, is hoarding corpses in
the basement. Her fellow sister wives are to be trusted one day and
feared the next, and Rhine is desperate to communicate to her twin
brother that she is safe and alive. Will Rhine be able to escape–before
her time runs out. http://thechemicalgardenbooks.com/wither/
