Unfortunately, for me the 2nd part of the duology could not match the quality of the 1st book. I really liked The God & Gumiho and eagerly awaited the continuation.
It's not a bad story and I still recommend reading it, but be aware that it has suffered from the current Romantasy issues of tropification & convenience editing to appeal to a mass of younger female readers, who have read and enjoyed many similar books before.
Whilst I acknowledge that we have some character development in our trickster god Seokga and the overall idea with the ship cruise and drama was interesting, the execution lacked and some of the new characters introduced were totally inconsistent.
Mainly I am speaking about the female lead Kisa, who cannot by any means compete with the charismatic and experienced Hani from the first book, whose reincarnation she presents. I appreciate that the 2 women needed to have major differences, but Kisa's character made no sense in many ways. Telling us she was working as a doctor in the maternity wards of a magical hospital for years delivering babies, but lacking the maturity that a job like that brings automatically, also in regards to sexuality. She was 22 years when she died but worked 7 years in the underworld, which makes her close to 30 years but she reads extremely young - a move to keep the character as close to the targeted reader as possible. Even if not everyone has to have sexual experiences at all, there is no must in human lives, her way to work in her profession stands in total contrast to how she acts around Seogka, and her inexperience is questioned once she starts getting naked and having a pool thing with the god.
Also the sudden appearance of the god emperor Hwanin as a baby - even if it is explained contextually and acts a funny detail of brotherly annoyance for Seokga - adds a weird mature moment, where all of sudden everyone becomes an adult, protective, snuggly and focussed on reproduction. In regard to the storyline the baby is a liability and sucks the fun out of the murder mystery it is a product of. In regard to romance, please choose between either sexy and naughty or family vibes and responsibility.
The side-kick Hajun, a former k-pop idol who took his own life and who was a brilliant idea on paper, never became real because here the fact, that the author and all editors of this story were female, showed the most. The way he spoke in general, thought and also acted around his love interest Somi, never even remotely sounded like a guy. Without simplifying men and reinforcing gender cliches, there are differences in what men would speak about, to whom and when - how they look at a situation and internally evaluate, where they would hold things back, even if they feel them etc. It's a typical problem within many genres when women write men, but especially when romance or any kinds of emotional responses are involved.
I enjoyed the mythical creatures and legends, the mystery part, the actions taking place on the ship - which could have been more detailed but the romance was the focus - and Seokga in general, who was himself but with a certain amount of growth. Yet his infatuation with Kisa is not plausible, especially in comparison to her former self Hani, who excelled as a main lead in the 1st book because she was multi-facetted and not a little, innocent, frightened damsel in distress.
I hope the author will get back to her old form in the next book she publishes, which I very much will want to read, but I would highly suggest to stop writing for a market and a typical target group, instead prioritise a good story and its unique nuances. The new adults of GenZ all will get older and even now deserve to be challenged with good and diverse stories that make them think.
