Books like Freefall

Apparently I'm stuck with this series, since I bought the first 4 books 'blindly'I love the idea of going Underground alright, just hated the prolonged writing style..But this one bit faster, cause here's a Freefall..to the Center of the EarthWith a Mason like cult, the Illuminate, the lost civilization of Atlantis..AND the theory of Hollow Earth..Now that the Urban Fantasy is back with more focus of the plot in the Topsoil, and the element of the old Science Theories, things getting much interesting now like the first half of book one, yet it still could be better told in less than 600 pages..More on the Characters will be added soon ISAMohammed ArabeyFrom 6 December 2018To 10 December 2018
