Remembrance Lost by Arian Williams

Clueless MC with amnesia
Hopelessly romantic other half
Special coffee thermos messages
Crazy teleportations across the world
Battle for one who needs redemption
Rescuing a trapped hacker
And mistaken and lost identities
Ryan met his soulmate when he was fifteen. And for him, it was a love at first sight.
Nikki was sixteen, an orphan who came to live with his family with no memory of who he’d been.
Five years later, Ryan’s still unsure whether there’s something more between them other than platonic love. They’d bonded in every way, except as lovers.
Then the world of Tasier intrudes, a hacker in danger in need of a rescue and a brother who needs redemption. Nikki and Ryan, along with their friends, travel across the world and are met with astonishing adventure and danger. With Nikki’s lost memories haunting them, will their bond be strong enough to survive the darkness that surrounds them?
