Nathaniel Fludd's life has taken a turn for the worst. With his parents lost at sea, he lands on the doorstep of a distant cousin-the world's last remaining beastologist. Soon Nate is whisked off on his first expedition, to Arabia, where the world's only phoenix prepares to lay its new egg. When disaster strikes, Nate quickly finds himself all alone. Will he be able to see the phoenix safely hatched, keep his accidental pet gremlin out of trouble, and rescue his guardian from the Bedouin? If he fails, nothing will stand between the world's mythical creatures and extinction. Too bad Nate's not the sort of boy who enjoys adventure . . .yet.

After tangling with the deadly basilisk, Nathaniel Fludd is glad to return to England with his Aunt Phil. But someone has ransacked their home, and their best suspect is the sinister man who's been trying to steal the Book of Beasts. Before Nate and Aunt Phil can find the culprit, they are called to Welsh countryside. The wyverns (giant dragons) are in an uproar. Could the same man who ransacked the Fludd house be behind the rift with the wyverns? And just what does he want with The Book of Beasts? But before Nate can solve that mystery, he must calm the dragons before it's too late. It's just another day at work for the world's youngest beastologist!

Theodosia Throckmorton has her hands full at the Museum of Legends and Antiquities in London. Her father may be head curator, but it is Theo-and only Theo-who is able to see all the black magic and ancient curses that still cling to the artifacts in the museum. When Theo's mother returns from her latest archaeological dig bearing the Heart of Egypt-a legendary amulet belonging to an ancient tomb-Theo learns that it comes inscribed with a curse so black and vile that it threatens to crumble the British Empire from within and start a war too terrible to imagine. Intent on returning the malevolent artifact to its rightful place, Theo devises a daring plan to put things right. But even with the help of her younger brother, a wily street urchin, and thesecret society known as the Brotherhood of the Chosen Keepers, it won't be easy . . . she quickly finds herself pursued down dark alleys, across an ocean, through the bustling crowds of Cairo, and straight into the heart of an ancient mystery. Theo will have to call upon everything she's ever learned in order to prevent the rising chaos from destroying her country-and herself!

Theodosia Throckmorton is in a fix. Allowed to attend a reception given by one of the directors of her parents' museum, she stumbles across Mr. Tetley of the British Museum-in most unusual circumstances! Since Theo has last seen him in a showdown in an ancient Egyptian tomb, his reappearance could mean only one thing: the Serpents of Chaos are back. Once again Theodosia will have to take on secret societies, evil curses, and dark magic too sinister to imagine, especially if it falls into the wrong hands. Blocked at every turn, Theodosia will have to rely on her own skill and cunning-along with a little help from the most unexpected places.

Being able to detect black magic isn't all tea and crumpets-and for Theodosia Throckmorton, it can be a decidedly tricky business! When Sticky Will drags Theo to a magic show featuring the Great Awi Bubu, she quickly senses there is more to the magician than he lets on, setting in motion a chain of events she never could have bargained for. Meanwhile, back at the Museum of Legends and Antiquities, Henry is home for the spring holidays and makes an accidental discovery of an artifact that alchemists have been hunting for centuries. Soon, every black-cloaked occultist in London is trying to get their hands on it . . .

In this fourth book in the series, Theodosia sets off to Egypt to return the Emerald Tablet-embedded with the knowledge of some of the ancient world's most guarded secrets. Accompanied by her cat, Isis (smuggled along in a basket), Theo plans to return the artifact, then explore the mysteries surrounding her own birth and oh, yes- help her mother dig up treasures on her archeological expedition. But nothing ever works out as planned, especially when a precious treasure appears suddenly, and then just as suddenly disappears . . . When the Serpents of Chaos get involved, Theo finds she's digging up a lot more than she expected!
