Dragon and Soldier

Jack Morgan 14 aka Montana enlists with youngest trainees for Whinyard's Edge mercenaries, hired by Parprin daublite mining colony humans from "Agrist claim-jumpers", who in turn employ Shamshir mercs. Honorable warrior-poet Draycos 30ish hides as 2D tattoo on Jack's back, and encourages noble values while their space-ship Uncle Virge continues the tradition of his late selfish Uncle Virgil, con artist. Recruit Alison is expert, already has militia experience - and secrets. Somehow, the duo must track down who attacked Draycos' scout ships before the refugee ships arrive to be ambushed.
