ive read 1&3 and i loveeeee them. ill check out the 2nd one when i get home, it looks really nice! thank you :)
honestly, i completely omitted the fact that home far away counts as something with a religious theme too, but i remember it really left me thinking when i read it LOL. i feel like its more about religious guilt than religion in general. absolute classic tho
