in a youth novel about adoption, abortion doesn't even exist

I am reading a YA novel about adopted people connecting with their biological siblings and parents. This is a topic I have written about and have an interest in, and it's supposed to be a very good book: Far From the Tree, by Robin Benway.

On page 3, the teenage protagonist knows she cannot raise a child, so she immediately begins the adoption process, interviewing prospective parents during her pregnancy. Fine. The word abortion is never used. Not fine.

There is no "She knew she would never have an abortion, so she...", no "It was too late to have an abortion, and anyway she doubted she would do that...", no "She was from a religious family, so abortion was out of the question." Not one word. As if the option does not exist. As if abortion itself does not exist. How realistic is that? Not at all?

Such is the state of YA in the United States. Does the author, or perhaps the publisher, think if the word abortion appears once in a 300-page book, the book will be the target of boycotts? Even in a book where the girl doesn't terminate the pregnancy? 

In case I was missing something, I searched the e-book for the word abortion. Not found.

I honestly don't know if I can get past this to read the book. My head is exploding.

I've written about this before, and at the moment I don't have time or inclination to add context. So: wmtc:

on tv, pregnancy is fine and dandy, but abortion is the choice that cannot be named (good comment discussion here)

murdoch mysteries, abortion on tv, and maybe an anti-war reference, too
