Tomebolo

An imperative throws the eye into the middle.
Should it come down facing inland or to the island?
The right tone whips a syllable end over end.
An X-ray shows holes on the plan of the tastebuds.
In the index of tonic reflexes, pages hide tombstones.
Immune cells are known to rearrange for antibody diversity.
What we think the reader sees: tondo.
