Really really unfortunate because I was excited to read this - zombies + romance + undertaking + western + letters seemed like a winning combination but alas. I don't super like the main characters (although I love the side characters) and at this point I can taste the third act breakup miscommunication shenanigans and I know for a fact I don't want to read 150 pages of that. 
I feel like if this was shorter, I could push through and potentially enjoy it but this just isn't for me which is a real shame.
