Mouse Bones by Kinsey Presley-Hornung

After her untimely death, Agnes wakes up on a college campus… in purgatory.

She’s been selected for admittance to Revenant Academy- the leading institution in posthumous education. While Revenant Academy might look like a picturesque college campus at first glance, it’s crawling with extinct animals and a labyrinthian archive of the dead.
When Agnes’s sorting goes awry, she finds herself with more questions than answers, but the school makes it clear that if she can’t leave her mortal secrets buried, she’ll be “expelled”. But it’s not just the past that puts her at risk. After she’s attacked by one of the mysterious creatures that lurk in the dark wood surrounding campus, her devilishly attractive Transparency professor is tasked with teaching her how to defend herself before the beast has the opportunity to strike again.
As their attraction grows and Agnes’s curiosity about her death deepens, she soon realizes that Revenant Academy is not entirely what it seems. Someone in purgatory has an agenda, and she’s a part of their plan, whether she likes it or not.
