On Demon Wings (Experiment in Terror #5) —> slight spoiler alert! (barely but, just in case you haven’t read the books preceding this one, skip this review and check out this reading order guide instead: Karina Halle – Experiment in Terror Series Reading Order)
*sigh* One of my BEST. Series. Ever! Bittersweet goodbye for now, as this is the last, but not least, in my Experiment in Terror reading marathon (for now…). Book #5 (the latest release that I received from the author, in this expected 8 book series) did exactly what all of the others did. Put me in an emotional tailspin! Another un-put-downable, creepy-as-heck read (maybe even creepier then all of them). Plenty to fear in this one, since it might not just be ghosts terrorizing Perry anymore. There is something much more sinister at work. Meaning… if you read this at night, do so with the lights on.
