Chasing Chaos: ALIAS International
Annie Miller

Former MI5 analyst, Ryan Butler, has followed the rules his entire life. He served his country, loved his family, and kept his mouth shut when he stumbled onto a biochemical weapon hidden at his father's house. Everything changed when his wife was murdered and the only suspect is the father he'd lost trust in.
Then walks in Chaos.
Daisy Chambers has one rule that she lives by... have no regrets. So when her hacking identity, Chaos had been leaked she had no other option but to go legit and work for ALIAS in their England location. It wouldn't be bad, she told herself. She could play by the rules... until she meets her new boss.
Together Ryan and Chaos team up to find who is responsible for his wife's death and who is trying to steal the vials of toxins.
They discover more than they were preferred for.
All Ryan knows is that no one has affected him as much as Chaos has. He'd do anything, including chasing her to have a future with her.
Only, chaos begets chaos, or so it would seem.
