Which One

Well its been a very quiet day and i need a little advice.  I am currently writing my second novel in my fantasy series and also working on my second book of poetry.  I am also wanting to write another book and have three synopsis for new stories.  I would appreciate if you would read all three and then leave a comment as to which you think would have more potential.  :)

Book 1

Cal Johnson is a mild mannered everyday run of the mill guy.  One day he drives his car at full speed into a concrete pillar and is engulfed in a ball of flames.  He walks away from the car.
Alison Stanton loves her husband of four years.  On the same day she slaughters him with a carving knife and sets fire to the house as she sits in a chair and burns.  She walks out of the house unmarked.
David Anderson works as a draughtsman.  He kills his partner and destroys their office.  Throwing himself from the top floor of the fourteen story building they work from.  He gets up and walks away.
On one day over 3,000 more people will choose to kill the ones they love, take their own lives and walk away unharmed.  Every one of them heads in the same direction, but where and why?

Book 2.

Garata has held court over the cloud kingdoms for more years than he cares to remember.  There has been peace and prosperity while he has ruled.  When he is slain and a new man takes over the darkness that has lain far away begins to descend.  A journey to a distant land might be the only way to save the kingdom, but none that have dared to venture have returned.  Who knows what lies beneath the Cloud Kingdom.

Book 3

Detective Alan Merchant has been a detective ten years.  In that time he has dealt with the dark side of humanity and all it has to offer  He thinks he has seen everything until now.  Two bodies are found in a park both seeming to carry no wounds.  When a newspaper is found underneath one of the bodies it shows a picture of the same two men, both dead alongside each other, the problem is the date on the paper 14th June 1936.  The year is 2019.

Just some ideas for stories and i think they all have possibilities.

Any help appreciated.
