Treasured by a Tiger by Felicity Heaton

Despised by his tiger shifter pride as an abomination, Grey has ventured far from home, deep into the bowels of Hell in search of answers about the machinations of Archangel, the mortal hunter organisation who held his twin captive. With no knowledge of the realm, and little skill with the local languages, he quickly finds himself at a dead end—until he crosses paths with a beautiful hellcat female who rouses his darkest most dangerous instincts.

Lyra has been a fool, falling for the charms of a male whose only desire was to make a fast buck by selling her. Shackled and collared, her strength muted by magic, she awaits her time on the stage at a black-market auction, but before it can come, all hell breaks loose and she seizes a chance to escape—and runs straight into a majestic warrior who steals her breath away and tempts her like no other as he battles alone to free everyone.

When Lyra offers her services as a translator to repay Grey for saving her, will he be strong enough to resist the needs she awakens in him and spare himself the pain of her inevitable rejection when she discovers the truth about him? And when the powerful male in charge of the slave ring starts a bloody hunt for Lyra, can she escape another collar and find the courage to trust the tiger who is capturing her heart?
