Christianization/Colonization of Pacific Islands

Hello!

I recently finished Cloud Atlas by David Mitchell and the Adam Ewing chapters really stuck out to me. More specifically, when the ship briefly stops in Raiatea. This passage in particular:

"The Christ Guards gives any Black who set foot here now a hefty flogging. Or would do. The Native children don't even know the names of the old idols. It's all rats' nest & rubble now. That's what all beliefs turn to one day. Rats' nests & rubble."

This piqued my curiosity regarding the effects that colonialism and/or Christianization had on the pacific islands. Any suggestions on this topic would be most appreciated!
