I really enjoy Cara Bastone's audio originals. They aren't 5* (topics of discussion, one I want to keep and re-experience, make you thinkg/ponder) ... but they are absolutely enjoyable and ones I'd recommend. I miss having a text copy for reference. I love listening, and the audio is great, but I like to flip through the text after/while listening, make notes, double check that I've caught everything. These originals are audio only.  Can't remember if there was any proFanity (that's something I can double check in Kindle). Recollection is PG rated. Cute. 

This had a bit of an Abby Jimenez feel to me ... maybe in part because Zachary Webber was the main male narrator. I tend to make associations with voices. But it was similar in the romcom feel. Two people meet on a bus, craziness ensues, there are sparks ... As much as I adore these types of meet cutes, I always wonder a bit "will it work out for them" if we were to have a continuation of the story? 

This is in the Love Lines "series" but I don't know that there were any connections to the first two (which I have listened to, but don't really remember). Absolutely could be a stand alone.
