3.5 stars
While I disliked the idea of the guy sending letters as his annoying and snotty sister, I liked the couple well enough that I was willing to forgive the deception to a certain extent. Still, I can't say I liked the setup being based on a lie even though I really loved the other aspects of the story and the pen-pal trope.
Definitely continuing on this series and reading a lot more by this author.
