If you're into speculative sci fi and/or mystery novels, I highly, seriously, super-duper really muchly recommend Ben H. Winters' The Last Policeman trilogy. I devoured the last two books in a day and a half, cutting into my own writing time. That's a problem.
And here's a brief description of the first in the series:
"What’s the point in solving murders if we’re all going to die? Detective Hank Palace has asked this question ever since asteroid 2011GV1 hovered into view. Several kilometers wide, it’s on a collision course with planet Earth, with just six precious months until impact.
"Industry is grinding to a halt. Most people have abandoned their jobs. But not Hank Palace. As our story opens, he’s investigating the latest suicide in a city that’s full of suicides—only this one feels wrong. This one feels like homicide. And Palace is the only one who cares. What’s the point in solving murders if we’re all going to die?"
