This is a quite small island, so unlike for others islands, I wont leave many comments here, just the picture of the style and flower location in the order you should (probably) find them. Additionally, no pictures about book table locations for this island:
You need to cross a gap on the wall as a bridge isnt lowered. You could go down at the middle of the gap and so you could eventually reach this flower.

At the very beginning of the area, in some kind of pre-area where you need to open a gate first for your ship.
Still in the same pre-area.
Style 3 and 4:
These are at the very same area, when you facing one of them, then the other should be behind you.
When you see the orb(seed) just ignore it first, go to the behind of the building there you can climb down to a platform where you can find the first book.
After using an elevator you can find the next style.
Style 6 and book 2:
Once you will get to a gap and you see a tower in the distance, then turn left to see the style. After jumping through the gap turn left again to see the table with the book.
While progressing there will be stairs to your right, leading to an elevator. If you go straight instead, then you will get to a climbable wall and with the book table on the top of it.
Style 9 and book 4:
Once you got the seed again you will see an elevator. Instead using it look around, there is a small area with the last style and book collectibles for this area.
Use the previously mentioned elevator but don’t use the seed/ball. Just drop it, go to the other side of the roof and climb down to the flower, which was visible already previously (this picture was taken from there)
