The books sent to Grace Field House by William Minerva are all very subtle messages for the kids, from what the orphanage wants to do with the kids to how to survive should they manage to escape. Minerva's stamp (ex libris) on the inner front cover of selected books has imperfections on the ring surrounding its owl emblem that, upon closer examination, spell out words in Morse code, for instance, and that is the least hidden of his messages.

These ex libris in the books were discovered by Phil and were further exposed by Emma. The following are the terms that can be seen.

Origin
Morse code is a cipher that encodes text characters as standardized sequences of two signals, "dots" and "dashes". The morse code is first invented by Samuel F. B. Morse in 1838 to send signals by telegraph.

Morse based his code on short and long buzzes. When the code is written out, a dot represents a short buzz and a dash a long buzz. When Morse code became widely used, S.O.S. (··· ––– ···) was chosen as an international distress signal because the combination of the letter O's 3 dashes (–––) and the letter S's 3 dots (···) is easy to transmit and recognize in Morse code.

Usage in the story
Eventually, William Minerva chose the Morse code as a method to warn the orphans of the secrets and dangers lurking inside and outside the orphanages. Minerva owned several books which have his logo attached to each of them as Ex Libris, they were later exported to the libraries of the premium farms. These Ex Libris are specifically directed to the orphans as secret messages for them to decode.

After decoding
William Minerva's hidden morse code, once deciphered, will convey messages to the orphans.

Promised Forest Arc
After the children escape from Grace Field, they discover that the Promised Pen has Morse code on the virtual navigation map which translates to "Touch Me". After touching the map, a box pops up with a virtual keyboard and the numbers "13-18-02". The children then realize they need to type a password into the box and that the one book from Grace Field's library that contained Minerva's owl bookplate but had no Morse code contains the password. By opening the book to page 18 and going to line 18, the second word is "Human" which turns out to be the password. After entering "Human" into the box a message from William Minerva telling the escapees to head to B06-32 is revealed.
