Afterworlds

Scott Westerfeld is renowned in the YA fiction market, this is a perfect blend of contemporary love story and fantastical thriller.
Darcy has secured a publishing deal for her three paranormal books. Now she must find the wherewithall to write the second one whilst she has a reprieve from going to college, thanks to her savvy sister. She has enough funds for 3 years in NY... if she eats only noodles every day.
In the story Darcy has written, the character Lizzie survives a traumatic shooting event only to discover that she has become a phsychopomp; a spirit guide to the dead. But she's not dead.. or is she? With one foot in each world, Lizzie's challenges are somewhat unique. Then there's her hot spirit guide... and all those ghosts that keep appearing... and the 'living' friend she usually tells everything to...
More than all I'd seen and heard.  It was coming back to life that made me believe in the afterworld.
