Somehow, Mercury is back in retrograde. For those who care (and maybe those who are sick of hearing the phrase blindly), astrology program Co-Star comes to the rescue. The A.I.-driven app is able to generate your astrological chart in order to provide daily horoscopes and to compare your chart with those of your friends. A newly launched feature allows users to ask Co-Star questions, such as “Should I get back with my ex?” Thankfully, its creators have worked with therapists and other mental-health professionals to craft the answers (meaning you most likely will not be told to get back with your ex). But who knows what’s written in the stars? For those in New York, ask questions to Co-Star’s Zoltar-inspired machine, at Iconic Magazine on Mulberry Street for the rest of the month.

The title of Luke Russert’s memoir takes its name from something the author’s father, the celebrated news anchor Tim Russert, used to tell Luke when he was little, in case he got lost. Fast-forward to a summer day in 2008, when Luke couldn’t look for Tim anywhere—he’d suffered, suddenly, a fatal heart attack, leaving behind his wife, the fearless Vanity Fair journalist Maureen Orth, and a 22-year-old Luke. The next few years saw Luke pursue a career in television similar to Tim, before realizing that chasing his father’s legacy wasn’t the thing for him. So he set out to find answers to the age-old question of what to do when you grow up, traveling to faraway places, from Paraguay to Vietnam. The result is Look for Me There: Grieving My Father, Finding Myself, on sale this week. ($28.99, bookshop.org) —Julia Vitale

Since its founding, in 1830, the French orfevrerie maison Christofle has married its traditional silversmithing savoir faire with the innovative artistry of everyone from Man Ray and Gio Ponti to Karl Lagerfeld. Now the Paris-based architect Elliott Barnes—a protégé of the legendary interior designer Andrée Putnam, who herself created a range of distinctive accessories for Christofle—is the latest luminary to join the heritage brand’s stable of cutting-edge collaborators. Celebrating the ritual of champagne, Barnes’s limited-edition, highly polished collection includes a two-bottle vasque, a single-bottle bucket, and a stainless-steel saber, all of which are twisted by hand into smooth, seamless forms by master craftsmen in Normandy.

Dive into London’s diverse food scene with this brand-new book from artist and author John Donohue. Somewhere between a travel guide and a curated restaurant-postcard collection, A Taste of London features more than 100 of the city’s best venues. Minimalist line sketches depict a wide array of London restaurants, from hole-in-the-wall spots to Michelin-starred dining rooms. Anecdotes from patrons, interviews with chefs, and Donohue’s own memories help to flesh out the illustrations. Whether it’s a description of a beloved institution, such as Ciao Bella, or an introduction to a hot new destination, A Taste of London has something for everyone. For those who suffer from wanderlust, read at the risk of purchasing a spontaneous plane ticket to Heathrow. ($27.50, amazon.com) —Paulina Prosnitz

No one does floral dresses with panache and day-to-night versatility quite like designer Erdem Moralıoğlu. And so, just in time for bare-legs-and-sleeveless weather, an addictive Erdem capsule collection has landed on Net-a-Porter. There are those sweet little prints, saturated pastels, and even a bit of bridal (including one sequined dress that involves, intriguingly, a cape). But we’re partial to the cotton-poplin Azami gown, with its ankle-length tiered skirt, romantic straps, and watercolor floral print. It wouldn’t look especially out of place on the beach, but it’s nicely suited to dinner at Raf’s. ($1,345; net-a-porter.com) —Ashley Baker

With all due respect to Azzedine, Alaïa’s current bout of greatness is thanks to the good work of the house’s newish creative director, Pieter Mulier. A longtime consigliere to Raf Simons (at both Christian Dior and Jil Sander), Mulier is equally adept at designing ready-to-wear and accessories; this season, it’s all about the shoes. We started with the fishnet ballet flats and then moved on to these laser-cut suede numbers; the slightly rounded toe and padded insole ensure that they, too, were made for walking (especially in the city), while the silhouette works swimmingly with skirts, trousers, and jeans alike. A classic ballet flat, but upgraded. Considerably. ($781, mytheresa.com) —Ashley Baker
