Rough start that gets better
Harem lit with adult situations, first person
The first part of the book is gripping with a well-done sea rescue suddenly goes wrong. For the MC, Ben, this serves as the transition to an alien planet. Since it takes place in the Bahamas, this could be an homage to the Bermuda Triangle and stories of vanished ships and aircraft. There's quite a bit of profanity in the first half; an attempt I think to prove how manly the MC is, but thankfully it eases back in the second half. There's an unnecessary comment about "weepy chick stuff", but the author thankfully focuses on showing that he cares tor the women, rather than indulging in stereotypes. These dings nearly made me select 4 stars, but the story did improve.
I have the impression the village comprises thirty to fifty individuals, but that's never discussed. Since it's an island, it must be a rather big one since it once supported a much larger population.
While there were no real surprises, the writing was good with a strong opening, and the story got better as is progressed. Definately will buy book 2. Recommended.
Spoiler alert ***
Part of any good fiction, including harem literature, is the relationships. Jacobs does a good job creating distinctive characters for the MC's inner circle. Since all the other males having died leaving many lonely women eager to babies to perpetuate their race, one of his jobs is to repopulate the island. At book's end, after three months, there are two, possibly three pregnancies. With 30-50 women in the village, he's not working very fast, especially considering a big difference with humans. What difference? It's a big one. The native females complete gestation in three months, not nine. This accelerated birth rate is accompanied by a shorter lifespan, too. The dragons, too, apparently live at an accelerated rate as well. It's not discussed, but it's a question whether ALL the life on this alien world are shorter-lived.
A second thing that stood out was about halfway into the story, the MC is transformed into the male version on the monster race, the dragon-kin. The MC barely considered this, readily accepting this change without a second thought. For readers, he started out as human, so maybe there is enough investment to keep reader interest; becoming alien severs a reader-hero connection, so it puts more emphasis on empathy built to that point and the strength of the writing to keep reader interest.
Part of the attraction of "monster girls" is the notion of interspecies sex or even breeding. Ben even wonders if they're even compatible. He's assured the women are mammals, too, and sure enough, once is enough to knock up two of the three main love interests. With the MC now changed into a male version of the species, however, there's no big deal about alien males having sex with a lot of females. At one point, one woman tells him that while they had mates, the males often serviced unpaired females. The taboo of breaking the Western sexual practice of monogamy is thereby defused. It's no longer, gasp!, this human guy is banging many monster females and trying to have babies with them, but aliens with socially weird (loose) sex practices.
The stated reason for this transformation is to facilitate his link with his dragon partner, but the fact that Ben is fertile with these women prior to becoming an alien male weakens the impact of the transformation. Indeed, the women only appear to have reptilian traits with some floppy ears and scales, but they act pretty much like human women. That's not a minus for me, just anobservation.
That's my take. Your mileage may differ.
