It's due out soon...ish, but I haven't said much about what it's about...
Last year, Cierra tried to kill herself and instead discovered a secret portal to another world. Encouraged by the people she met there, Cierra finally felt like she made some headway against her depression. Until she receives a suicide note from her best friend, Olivia.
With Olivia in the ICU, Cierra struggles not only with the guilt of not seeing her friend's pain, but against the mental illness she thought she'd beaten.
Worse, a dark secret from Zach's past draws Cierra back through the portal and threatens to separate her from everyone she loves.
And now you know :)
