A little slow at first, the story line definitely picked up as it moved along, with both the character development and action improving until it reached a satisfying conclusion. The story is one where Noah Simmons, killed in a cave by an unseen evil presence, haunts a group of scientists who enter an underground network of caves for a six-month scientific experiment. The group, headed by Ethan Winslow, has Liz Madison on the team among others. To enable both to be on the experiment, Ethan and Liz marry and the story deals with their attraction and, ultimately, love for one another. The evil presence is a good background and is not overplayed at all. Noah is a cowardly ghost, unable to battle the evil until the end, which is a bit tiring after a while. The man is dead already! Ethan wrestles with not wanting to love Liz, and that is ultimately a little wearing, but seems to reach a natural conclusion. Liz has a secret relationship with the experiment's "founder" -- Aaron -- and the reason for their relationship, and the ensuing gossip and jealously on the part of Ethan, is, to me, the weakest part of the story. The end is done in a few pages, the secret is revealed, and I was tempted to say "That's it? You were willing to ruin a relationship with Ethan for that and yet you happily divulge it at the end?" But that is the only real dissatisfaction I had with the story. Overall, an enjoyable read which blended the horror and romance rather well!
