Dark Parallel - The Joshua Files

Josh and Ixchel have travelled back in time, but it might not be so easy to get home again. They've landed in the Mayan era, when the prophecy about the world ending in 2012 was first foretold. And they cannot believe who they have found there. Clearly Josh isn't the only person to have cracked the secret of time travel. But a bigger surprise awaits the pair when they return to the 21st century. Nothing is quite as they remember it - and it's up to them to work out why.
