Warrior Blue by Kelsey Kingsley

Blake Carson can’t afford to have a life. Between working full-time as a tattoo artist and caring for his disabled twin brother Jacob, his plate is more than full – and he prefers it that way.
But his meticulous planning is turned on its head when he meets the upbeat and beautiful Audrey Wright and her butterfly tattoo.
Now, through a complicated maze of coincidence and fate, Blake begins to question if maybe there could be more to his life than just work and Jacob.
That is, if the guilt doesn’t eat him alive first.
With the help of Dr. Vanessa Travetti and a girl he doesn’t think he deserves, can Blake convince himself that even the bad guy deserves a happy ending?
