Books in Guild of Specialists series
Attitude: Unobjectionable → Positive
Becca & Doug McKenzie become involved with the Honourable Guild of Specialists when their parents disappear, leaving them in the care or their uncle, captain of the research boat _Expedient_.
Slightly larger-than-life heroes and villains; a broad cultural sweep to the front and backstories; unremarked equality of men and women; courage and steadfastness among (heroic) allies. Impetuous if well-intentioned disobedience and deception by the children.
