Meg: Hell's Aquarium is a 2009 science fiction horror novel by American author Steve Alten. It is the sequel to Meg: Primal Waters and the fourth book in the MEG series. Described by Alten as "the pinnacle of the series", the novel continues the adventure of Jonas Taylor and his family, as his son David, hired as a handler for two megalodons (megs) being sold to a royal prince of Dubai, is tricked into overseeing an expedition to capture a Liopleurodon (Lio) from the remains of the Panthalassa, while Jonas, Terry, and Dani deal with a terrorist group seeking to unleash the remaining megs unto the oceans of the world. The novel's audiobook was narrated by Keith Szarabajka, with Lana Wood, a self-professed fan of the series, licensing her image for Alten to write in a fictionalised version of herself, promoting the novel then-after, Alten attributing the novel's delay to the development hell of The Meg.
