The following fonts are used in the Patriots series of books:
The Final Frontier font is a font designed by Allen R. Walden. This font is freely available from a number of font sites, and so is not available for download here. Final Frontier is used on the title page of the Patriots series of books.
Because Final Frontier lacks a copyright symbol, one had to be designed for it. The Final Frontier Copyright font is a single-glyph font that contains that copyright symbol, which was designed to complement the Final Frontier font. This font is bundled as a separate font because the Final Frontier font's license does not clearly grant permission to modify the font and redistribute the modified version.
This copyright symbol font should be considered in the public domain. In countries that do not recognize a creator's right to release a work into the public domain, you may use it under the SIL Open Font License, the MIT license, or any other license you prefer.
The DG Didot font is derived from the GFS Didot font, with a number of Latin alphabet glyphs updated to be more Didot-like. Licensed under the SIL Open Font License.
The Muesli font is a modified version of the Muli font. In addition to redesigning the quotation marks to be more visually distinct at a small font size, the font is re-kerned and the weight slightly altered to be a better visual match for the DG Didot font. Licensed under the SIL Open Font License.
The Telegraph Hill font is a modified version of Linden Hill, redesigned for use as a drop cap font. The major differences are that 'J' and 'Q' are raised to sit on the baseline, numbers are scaled and shifted to sit on the baseline, and the quotation marks are rounder. Licensed under the MIT license.
The Orbital Obliteration font is a modified version of the Orbitron font modified for use in displaying chapter numbers. It includes additional glyphs for making certain letters appear visually almost connected to adjacent letters.
This font requires a fully OpenType-aware renderer in order to obtain maximum benefit. This font is not intended for general text, and I have only tweaked the kerning/spacing and 'calt' tables for the characters that are actually used in spelled-out English numbers. Licensed under the SIL Open Font License.
This font contains blank glyphs instead of characters. It is used to display a warning to anyone whose EPUB reader is overriding the publisher-specified font. On compliant readers in the default mode, the warning text should not be visible, because this font contains entirely transparent glyphs. On any reader that is overriding the default font selection, the text becomes visible.
This font should be considered in the public domain. In countries that do not recognize a creator's right to release a work into the public domain, you may use it under the SIL Open Font License, the MIT license, or any other license you prefer.
