I liked seeing these more middle aged MCs having quite the adventure!

Celeste is asked by her friend Chris to partner with his friend John for some event but she gets the signals wrong. Suddenly she's the pretend new girlfriend of John in a birding contest!

This was a new type of adventure novel with the birding contest and I liked the uniqueness.  I really enjoyed the budding relationship with Celeste and John and the insecurities they helped each other with.
