God is an astronaut - Alyson Foster

As though a gesture could save anyone - in this universe where even the smallest pieces are hurtling away from one another at the speed of light.That's all then.
Or all I can say right now.What say you?Jess Frobisher is a botany professor at the local university. Her
husband, Liam, works for a space tourism company called Spaceco, which
has just become front-page news: one of their shuttles exploded shortly
after lift-off, killing everyone on board. The press descends. With the
future of the company in doubt, two filmmakers approach Liam about
making a documentary on the space tourism industry. Seeing this as an
opportunity to save Spaceco, Liam agrees to cooperate, assembling a team
for another trip into space. When he asks Jess to go, she must decide
how far she's willing to go to save her faltering marriage and her life
as she knows it.
