“Ezekiel must decide if he will join the ranks of a criminal mastermind, or fight to escape the tyranny that has surrounded his young life. Or even beat them at their own game.”

The novel was being sold on Amazon but appears to have been removed from its site.

The front cover says the story was inspired by true events.

‘A real connection’

New information also suggests that Ms Lueck may have been a sugar baby.

Ajayi and Ms Lueck had been texting each other and phone data showed them at a park north of Salt Lake City within a minute of each other, police said.

According to Fox News, an Instagram account believed to belong to Ms Lueck was active on Wednesday more than a week after she went missing.

The account liked a page called “Fatherless”, which has the description “I got daddy issues” in its handle.

Ms Lueck also reportedly used Facebook to share advice on having a sugar daddy, Utah newspaper Deseret News reported.

"Mine says 'I want a SD/SB relationship with a real connection’. If don't know what a SD/SB is, tell them bluntly sugar daddy and sugar baby. But if they don't know, they aren't really worth your time," the post states.

"Private message me, if you have more questions! I have experience."

The Zion’s Lost podcast, which focuses on missing people, reported Ms Lueck has a profile on the website SeekingArrangement.

The site is where “Sugar Babies enjoy a life of luxury by being pampered with fine dinners, exotic trips and allowances”, SeekingArrangement’s about us section reads.

“In turn, Sugar Daddies or Mommas find beautiful members to accompany them at all times.”

A spokeswoman for the site declined to say whether the 23-year-old was a member of the site as a matter of privacy.
