Which book do I read first from those lovely people at Head of Zeus?

There was a knock at the door, so I opened it and the post lady gave me a package with all these goodies, all from those lovely people at Head of Zeus.  Of course the top 2 are catalogues for current and future releases but I will read the 4 books at the bottom of the picture pronto; I just don't know which one to read first!  Probably be The Grim Company by Luke Scull as I have heard good things about this author whilst not actually knowing he was one of Head of Zeus's! Thank you to all at Head of Zeus for a good week (or so's) worth of reading material...  
I shall also give my reviews of each book.
