Mia Thermopolis knows just what to do in a crisis: Rule. During the Covid-19 pandemic, a section of the diary of Princess Mia Thermopolis of Genovia fell into the hands of Meg Cabot, the Princess's royal biographer. As reported in media outlets such as Entertainment Weekly, The Mary Sue, Refinery 29, Bustle, and more, from March until June of 2020, sixteen entries of the princess's diary were leaked onto Ms. Cabot's blog, to the delight of over a million fans. In these entries, titled The Coronavirus Princess Diaries, the princess recorded her most heartfelt emotions while dealing with her husband's quarantine after exposure to the virus; her personal (and political) battles while imposing health restrictions on her small European nation; life during lockdown (even in as idyllic a location as a palace on the Riviera); and of course, dealing with her demanding royal family, especially her grandmother. Since then, readers have been clamoring for more chapters of Mia's coronavirus diary . . . and here they are at last: The Quarantine Princess Diaries include not only the previously released entries (now edited and updated with new content), but two hundred more pages of entirely original, never-before-seen entries, including the princess's worries over a possible royal affair; a showdown between Mia and Grandmère over the latter's intended nuptials; the eventual development and distribution of a groundbreaking intranasal vaccine for every citizen in Genovia; and, as always, a royally happy ending. After all we've been through, what could be more comforting for any lover of royal romance than snuggling up with a brand new installment of the diary of Mia Thermopolis, the princess who started it all?
