Never Enough

Lane Lamore is a Boulder-based bounty hunter, insurance investigator, and science journalist who solves problems other people can't - or won't. She doesn't chase justice. She chases the thing that doesn't add up, and the fee that comes with making it make sense.
In Never Enough, Lane follows a missing prospector into the Sangre de Cristo Mountains and finds herself at the bottom of a mine shaft with a dead woman, a lithium deposit, and a rope that may or may not hold.
Getting out is only the beginning.
The third book in the Lane Lamore series, following The Wrong Feet and Sleight of Hand.
