Meant For The Cyborg Captain - Cybernetic Hearts, #4

Celestial Mates-Romancing the Galaxy.Human Heather Sanchez and the cyborg captain, MX409, have been working together for weeks-and he's driving her crazy. She doesn't have time to absorb the sudden epiphany that her annoyance springs from an attraction to the stubborn cyborg-an attraction that's clearly mutual-before they discover a secret synth base that could be the key to defeating their enemy forever.
They have to act quickly to avoid the amassing synthetic army, and if they aren't successful, it means doom for humans and cyborgs. Her thoughts should be solely on survival, not on anticipating claiming MX as her mate. Can a human woman find true love with a cyborg captain while fighting a massive army of synthetics? Find out in this latest installment in the Celestial Mates (and Cybernetic Hearts) series, brought to you by USA Today bestselling author Kit Tunstall, writing as Aurelia Skye.
