River Secrets (The Books of Bayern, #3)
Razo has never been anything but ordinary. He's not very fast or tall or strong, so when he's invited to join an elite mission escorting the ambassador into Tira, Bayern's great enemy, he's sure it's only out of pity. But as Razo finds potential allies among the Tiran, including the beautiful Lady Dasha, he realizes it may be up to him to stop a murderer and get the Bayern army safely home again.
