The second book in the Collector series was not what I expected, but I really enjoyed it nonetheless. I assumed it would follow more along with the life of the butterflies after the garden, which it did to a certain extent, but it was off to the side around another crime being investigated by the original FBI agents. 
Both stories interlinked and I really enjoyed following along.

Again, I listened to this one on Audible over a couple of days, going back and forth to work, and then the last 40% on my kindle to finish it off as I didn’t want to wait until Monday to find out how it ended. 

Looking forward to getting into the third book of the series :)
