YMMV / Adventure Series

• Ho Yay: Hal and his friend Omo are very close. They become 'blood brothers' on a deserted beach at night, swearing to be known in their hearts by each others' names, and Omo even takes a bullet for Hal later in the same book.
• Values Dissonance: the series is never explicitly racist, but some of the ways the Africans or native South Americans are described can make the modern reader wince occasionally.
