OH MY GOODNESS. Didn't see THAT ending coming. That was great! Wow. The narration lulled me into thinking that this would be a sweet story, sweetly tied up. Maybe ending with a prayer thanking God for the opportunity to care for the children. But nope, not happening. That was a fun read for sure.
I thought the narration was close to flawless until the part about the abortion. That jolted me as a reader; it felt too sudden and clearly drawn out. If it was a secret she kept from everyone, maybe the narration should reflect that by relating the abortion in a more hinting, gradual way, as if the narrator too is reluctant to give out this information. Then again, knowing the end, it almost seems fit that it should be so abrupt and relatively emotion-less. ;)
My other suggestion is about the Ethan scene, when he comes to Mack and Bama with his request. I felt disbelieving the whole time. I think it comes down to the dialogue, especially when Ethan says the part beginning with, "It will be a two year journey to several third world countries...." I mean this is a HUGE request he's asking of them, but it sounds flat and robotic here. So maybe if descriptions of Ethan being nervous, but excited, pleading, sincere, etc. were included - some details revealing this to the reader - this part would be more believable.
The last part, despite the suddenness and incredibility of it, was very believable to me. I thought it was a great twist. With that bit, the whole story was changed, which was a lot of fun for me as the reader. Ha ha. :)
just one typo I saw...
"didn’t you just live" --> "didn't you just love"
