Clever yet heartfelt sci fi from Vaughan and Staples. Lovers from bitterly opposing sides in a galactic war on the run in a plant-based space-ship with their baby and their ghostly baby-sitter and pursued by both a bounty-hunter with a lie-detecting cat who teams up with one of the lovers' exes, AND a royal prince from an android race who is allied to one of the sides, suddenly find this peaceful existence disrupted by the arrival of one set of parents. This they now do.
