The first three adventures in the Dragonback series.
 
Dragon and Thief: Young thief and con artist Jack Morgan is hiding out on an uninhabited planet after he’s falsely accused of a crime. But his solitude is interrupted when Draycos, a warrior whose reptilian race is being targeted for extinction, makes an emergency landing. The two will be able to survive, but only if they literally bond together . . .
 
Dragon and Soldier: When all is well, Draycos looks like nothing more than a tattoo on Jack Morgan’s back. But when Jack’s threatened, the K’da warrior appears in his true, dragonlike form. Together they go undercover to investigate a mercenary outfit connected to the extermination of Draycos’s people, and it turns out Jack isn’t the only new recruit with a secret . . .
 
Dragon and Slave: Following a lead, Jack becomes a slave on a Brummga alien estate where he must find out all he can while under the cruel watch of a vicious slave master who has no problem killing the help. Fortunately, Draycos always has his back.
