I'm playing catch up with these, recently having listened to Harvest of Souls and The Darkest Shadow.
Harvest of Souls I couldn't finish the first listen to, I wasn't in the mindset to listen to [spoiler]Maggie Evans attempt suicide[/spoiler]. I put it away for a couple weeks and pulled it out again and finished it. It was really bittersweet. The acting was pretty good, but I'm not entirely satisfied with the direction the characters went in.
The Darkest Shadow I finished this morning while at work. The first half was excellent, I loved it, tore my heart out in places! Then the second half happened and it all fell apart. Oh so many things so very wrong! And then they hamfistedly forced it to fit into The Haunted Refrain. The premise itself was good, but not the execution (IMHO).
I've heard Carriage of the Damned is good so I'm looking forward to listening to that next.
