Showing Exile by Nancy Foster

Two heroes are on the lam. Richard Earlrose is forced to flee to the Elf Kingdom in utter secrecy so that he can further his sorcery training with Lord Yu's help. While he trains nonstop in order to defeat his cousin Leilandy Aethinford that usurped his rightful throne, Spaulding is on a secret mission as well.

Tortured and isolated in the eastern territories for 5 years, the elf that committed an unthinkable capital crime has set off to locate something from an ancient scroll he destroyed during his imprisonment for an unknown purpose.

The ever deceitful Lord Froylan must choose where his true loyalty stands and form an unlikely alliance in order to settle the score and locate a new king for his nation before it's too late.
