The Heart Dove
I have read your first chapter and I'm sorry to say I had a hard time getting grounded in the story. I think it might have a little to do with all of the names/terms used in this chapter, especially some that weren't really given explanations. For example, you use many different names for Libum's master; God, Goddess, The Hummingbird God, the Death God, Kolupati and Lady Kolupati. I think it might be helpful to stick to one name, such as Lady Kolupati, and use the others and descriptors, like "Lady Kolupati, the Death God" and then continue with whatever she is doing. You don't need to use these descriptors often, just when you think the reader might need a reminder of what she is.
Another example is the other terms you use, such as bata, Tagkawal, and Anito. I am not familiar with these, although I'm not sure if they may be common terms used in other stories or myths, but if they are not common terms you may want to find a way to introduce them to the reader so they know what they mean.
After reading the chapter twice I got a better understanding of what was going on, but it shouldn't take two readings for a reader to grasp what you are trying to convey.
I will also admit I am pretty tired this morning and my brain may not be working at full capacity, haha, so I'm sorry if all of this is completely unhelpful.
With all of that said, I love the idea of a world in between worlds, and a young man getting fed up with his duties there. It makes me curious to see how he will perhaps avoid his responsibilities, and the wrath of his master if he decides to do so, although from the description it sounds like his next partner will liven things up for him at least.
Lastly, thank you so much for reading Gaijan, I'd love to hear more of your thoughts on it if you are willing to share them
