Wren Calder had three avoid emotional entanglements, fix the tech, and never trust a man who growls.

So naturally, she ended up on an alien planet, partnered with a tiger shifter who thought fated mates were a myth—until she rewired his defense systems and made his pulse crash like a corrupted server.

Commander Rylan Kaedor didn’t want a partner, much less a mate. But the moment Wren touched his firewall, both literally and emotionally, he knew two she was his, and he was completely screwed.

Now they’re navigating rogue hackers, rigged combat simulations, planetary politics, and a mate bond that won’t stop throbbing. She’s brilliant, mouthy, and refuses to call him “sir.” He’s growly, dangerous, and keeps offering to carry her home—on his shoulder.

Together, they might just win the Protocol Trials.
Or burn down the galaxy trying.

He didn’t need a mate.
Until she rewrote every rule he lived by.

Read on for alpha commanders, sarcastic Earth geniuses, sabotage schemes, and a tiger shifter who would rather bite than beg. HEA Guaranteed!
