The "rise of the warlords" by gena showalter is considered a spin-off of lords of the underworld. So, in this example, the immortal is book #15.75. Why the phantom is book #16? Both are part of the same spinoff, both have 300 pages, and they're expand the series, but are not a direct sequel.
TL;DR I ask that the phantom is renumbered based on this.
