Careless by Kelly Goode

The aliens didn’t invade Earth in giant spaceships as depicted in the movies – they were smarter than that.
Lydia Waters prefers dealing with dead aliens over the Invasive Species Control agents and has rightfully earned her reputation as “Ice Queen” within the unit.
After crashing to Earth, Jonah Parish went his separate way from the colony. He spends his days trading information and making money from gullible humans.
When their worlds collide, one careless mistake leaves Lydia and Jonah racing to find a cure for her mutation before she becomes the very thing that the ISCU unit hunts and destroys – an alien.
Can Lydia hold on to her heart and her humanity? Or will Jonah persuade her to give him both? Revisit the Invasive Species Control Unit, where defeating the aliens is no longer their hardest mission, it’s trying not to fall in love with them.
