This weekend Lesley Jones is running a 24 hour event in support of the Leukaemia Foundation. The event: https://www.facebook.com/events/289918687877680 . There will be 24 author take overs and there's a huge rafflecopter giveaway going on.
She is also having a sale on her books, Carnage and Saviour to raise money to donate. The entire proceeds from the sale of these two books will be given as a donation to the Foundation.
If you haven't read them, then you need to.
If you've got friends who haven't, then gift them a copy while they're on sale.
