THE POWER OF SIX

Henri's prior death shapes the story, and Adelina dies during a battle to save Marina; grief and loss affect the characters.

Injuries are described in the heat of battle, but it lacks excessive or gratuitous focus on anatomy or blood.

Occasional mild profanity or harsh language may appear in this high-stakes action story, but it is not prominent.

Setting characters within a religious institution (a convent) is a narrative choice rather than a focus on theology.

John reunites with his girlfriend, Six becomes another romantic interest, and a love triangle involving John, Six, and Sam is present.

Young characters are hunted by hostile aliens and authorities, ambushed repeatedly, captured, separated, and placed in life-threatening situations.

Repeated attacks, ambushes, chases, battles, imprisonment, rescues, and attempts to infiltrate an enemy base are central to the plot.
