Stripe Theory by Milly Taiden

When a Brilliant Scientist and a Brooding Tiger Shifter Team Up, Love Isn’t the Only Thing in the Air—So Are Explosions.
When Dr. Alora Sky, a tiger-obsessed genius with a love for stripes and sarcasm, lands a research deal with the enigmatic Kedi Biogenetics, she’s thrilled to tackle the mysterious virus threatening tiger shifters. But science takes a backseat when her lab is stormed, her life is threatened, and the annoyingly handsome Rehan Kedi—billionaire tiger shifter and the pride’s grumpy leader—insists on becoming her shadow.
Rehan’s life is all precision and control, until Alora and her chaotic brilliance crash into it, turning his world—and his tiger—upside down. She’s quirky, relentless, and completely unaware of shifter mating bonds. But as much as Rehan tells himself this is just about saving his sister and his pride, his tiger knows better. Alora is his mate, even if she’s too busy fighting off mercenaries with liquid nitrogen and naming her lab cat “Stripes” to notice.
With the future of tiger shifters at stake, Alora will need every ounce of her scientific ingenuity—and maybe a little help from the hunky tiger god following her—to survive. Can she save his sister and all tiger shifters or will their unexpected love be their downfall?
