The vampire diaries the fury by L.J Smith chapters 1-5

So Elena wakes up lost and confused she finds Stefan and Damon fighting in the woods, she pulls Stefan off of Damon and then surprisingly attacks him, it appears Elena has no memory of Stefan she seems to think she's in live with Damon. Stefan knows that Elena is a vampire and he knows she needs to feed on human blood to complete her transformation successfully. Matt is who he turns to helping Elena is what Matt has always done. Once fed Elena leaves with Damon leaving Stefan to face the grusome scene in the hut which is thankfully not so bad as the gang Stefan attacked to fill him up appear to still be alive. Elena wakes up in Alaric Saltzman's attic alone and confused, she can hear voices and goes to check what's going on, but she doesn't understand what she hears and she doesn't understand why she feels so afraid. Elena goes back to the attatic and reads her diary that helps her realise the blank spots in her memory, she has to see Stefan, leaving the attic she makes her way through empty streets passing the church she gets a need to go inside, sneaking into the choir stand she becomes witness to her own funeral and is upset by people she hardly knew speaking about her as if they were best friends. Stefan arrives and they share a moment until Damon arrives also, more strange things take place as a pack of dogs attack humans. It is then that Elena realises the danger Bonnie spoke about when she had visions wasn't Damon it's something a lot stronger than the three of them put together.
