[[Thirteen Reasons Why by Jay Asher]] takes another stab at the world of untimely teenage death, with promising results. [[The Lovely Bones by Alice Sebold]] is a not dissimilar story that might also appeal, though personally I found ''Before I Fall'' a tad more readable. If you like to suspend belief of what is possible in the worlds of time and space, [[The Time Traveler's Wife by Audrey Niffenegger]] is also worth a look, but start with this one first, it really is the best of the bunch.
