"Shadows Before the Sun" is the 4th installment of the Charlie Madigan series. Whether it is the final one remains to be seen but it did represent an ending to me.
Charlie needs to go to Elysia to find Hank. She did promise him that at the end of The Hour of Dust and Ashes. Their friendship is too important to leave anything to chance and the words of ambassadors. Right now Hank needs a friend who is willing to break the rules to get to him. Charlie and Allessandra, the Oracle, end up as travelling companions. They both consider the other a severe test of patience.
The world of Elysia turns out to be as bad as the Earth Charlie is from. There is plenty of political maneuvering, power-plays and mayhem. But there is also help from unexpected quarters.
Charlie's character has grown during her trip through these four novels. With her growth has come a better understanding of other people and perhaps even an ability to see them as individuals and not just part of some great mass that she has to keep safe.
We get action with plenty of fighting and some sex. I guess both could be considered somewhat adult in content.
My journey with the Charlie Madigan series has been a pleasant one. "Shadows Before the Sun" is easy to read, difficult to put down and fits the other three novels well.
