Name: Claimed by the Dragon Bond
Author: A R Lenahan

Why these tropes fit

Book Two of the Forbidden Riders series follows Elowen, the most wanted rebel rider, as she leads the Ash-Marked rebellion against the Order's bell-controlled dragon empire rather than flee. Evren, a scarred former Hunter whose memories are fractured and whose dragon is being reclaimed by the silver network, becomes bound to her through the dragon bond—his body and dragon remembering her even when his mind slips. Their forbidden, bond-driven romance plays out under forced proximity as a frozen wasteland closes in, Elowen's sister Mira fades from the Spire's extraction damage, and the Prime Bell retunes to drag every bound dragon back under command. The pair must strike the Capital before the final command is given, with their dragon bond serving as both Evren's anchor against becoming the weapon he was made to be and the rebellion's hope to shatter the bells.
